Access Answer to NCERT Class 10 Science Chapter 5: Periodic Classification of Elements

Below are NCERT class 10 science chapter 5 exercise solutions, organized by topic for better student comprehension and use:

Topic 5.1 Making order out of chaos - Early attempts at the classification of elements

Q.1. Did Döbereiner’s triads also exist in the columns of Newlands’ Octaves? Compare and find out.

Answer:

Yes, Dobereiner's triads also exist in the column of Newland's octaves.

Newland's law of octaves, says that every eight elements had properties similar to that of the first.

For example, the element Lithium, sodium, and potassium are present in the second column of Newland's classification of elements. If lithium is the first element then, the sodium will be the 8th element and considering again sodium as the 1st element, then the 8th element will be potassium.

So, that means according to Newland's Law of octaves, lithium, sodium, and potassium should have similar properties and also these elements form a Dobereiner's traid having similar chemical properties.

Q.2. What were the limitations of Döbereiner’s classification?

Answer:

The limitation of Doberenier's classification:

Döbereiner could identify only three triads from the elements known at that time. Hence, this system of classification into triads was not found to be useful.

Q.3. What were the limitations of Newlands’ Law of Octaves?

Answer :

The limitations of Newland's law of octaves are:

(1) It was found that the Law of Octaves was applicable only up to calcium, as after calcium every eighth element did not possess properties similar to that of the first.

(2) It was assumed by Newlands that only 56 elements existed in nature and no more elements would be discovered in the future. But, later on, several new elements were discovered, whose properties did not fit into the Law of Octaves.

(3) Newland put two elements together in one slot and that too in the column of unlike elements having different properties.

Example: Cobalt and Nickel were put together in just one slot and that too in the column of elements like fluorine, chlorine, and bromine which were very different properties from these elements.

  • Ba

Answer:

The general formula for the oxides of the element Barium (Ba): Barium belongs to the group II of Mendeleev's periodic table,

Hence, the formula of its oxide will be BaO.

Q.2. Besides gallium, which other elements have since been discovered that were left by Mendeléev in his Periodic Table? (any two)

Answer:

Besides gallium Scandium (Sc) and Germanium (Ge) elements have been discovered for which gaps were left by Mendeleev in his periodic table.

Q.3. What were the criteria used by Mendeléev in creating his Periodic Table?

Answer:

The criteria used by Mendeleev in creating his periodic table were:

(i) The atomic mass of the elements was used to arrange the elements.

(ii) Grouping the elements according to their similar chemical properties.

And hence proposed that the chemical properties of the elements are the periodic function of their atomic masses and thus he arranged the elements according to the increasing order of atomic masses.

Q.4. Why do you think the noble gases are placed in a separate group?

Answer:

Noble gases are inert nature elements. In the periodic table, they are placed in a separate group because they have a unique property and are very different from other elements.

Topic 5.3: Making order out of chaos: The Modern Periodic Table

Q.1. How could the Modern Periodic Table remove various anomalies of Mendeléev’s Periodic Table?

Answer:

Modern periodic table removes, various anomalies of Mendeleev's periodic table as follows:

(1) In the modern periodic table, elements are arranged in the increasing order of their atomic number, not in the atomic mass.

(2) In the modern periodic table, the isotopes are placed in the same place as they having the same atomic number but different atomic masses.

(3) Now, the same group elements have the same number of valence electrons.

(4) Hydrogen is now placed in the group containing the same valence electrons.

Q.2. Name two elements you would expect to show chemical reactions similar to magnesium. What is the basis for your choice?

Answer:

Elements that show similar chemical reactions are Beryllium (Be) and Calcium (Ca) because they belong to the same group. i.e., group 2nd in the modern periodic table

Q.6. (a) The position of three elements A, B and C in the Periodic Table are shown below–

Group 16Group 17
--
-A
--
BC
  • State whether A is a metal or non-metal.

Answer:

As we know in the periodic table, group 3 - group 12 are transition metals and group 13 to group 16 are metalloids and then there are halogens in 17 groups.

A is in group 17 so it is a non-metal.

Q.6.(b) The position of three elements A, B, and C in the Periodic Table are shown below –

Group 16Group 17
--
-A
--
BC
  • State whether C is more reactive or less reactive than A.

Answer:

Element C is less reactive than A because in the halogens the reactivity decreases as we move down. This happens because as we move down the nuclear attraction increases due to an increase in atomic mass. Stronger attraction toward electron will make it harder to react with any other element that's why they are less reactive.

Q.6.(c) The position of three elements A, B and C in the Periodic Table are shown below –

Group 16Group 17
--
-A
--
BC

Will C be larger or smaller in size than B?

Answer:

C is much smaller than the size of the B because C has a higher atomic mass which means higher attraction to the electron which means compact (less) size.

Q.6. (d) The position of three elements A, B ,and C in the Periodic Table are shown below –

Group 16Group 17
--
-A
--
BC
  • State whether A is a metal or non-metal.
  • Which type of ion, cation or anion, will be formed by element A?

Answer:

A will form an anion as it accepts an electron to complete its octet.

Q.7. Nitrogen (atomic number 7) and phosphorus (atomic number 15) belong to group 15 of the Periodic Table. Write the electronic configuration of these two elements. Which of these will be more electronegative? Why?

Answer:

The electronic configuration of the element Nitrogen (N) is (2,5) .

The electronic configuration of the element phosphorus (P) is (2,8,5)

So, Nitrogen will be more electronegative than Phosphorus because its atom has a small size due to which the attraction of its nucleus for the incoming electron is more.

Q.8. How does the electronic configuration of an element relate to its position in the Modern Periodic Table?

Answer:

The electronic configuration of an element gives the distribution of electrons in various shells present in the element. The atoms with similar electronic configuration are placed in the same column, hence groups have the same number of valence electrons.

Group number can be known by knowing the number of valence electrons.

The number of shells present in an element is equal to the period number.

Thus, the information of electronic configuration is enough to know the group and period number of an element.

Q.9. In the Modern Periodic Table, calcium (atomic number 20) is surrounded by elements with atomic numbers 12, 19, 21, and 38. Which of these have physical and chemical properties resembling calcium?

Answer:

Element with atomic no. 12 and atomic no. 38 will have chemical properties the same as calcium. this is due to the fact that they have valency the same as calcium and also lie in the same group.

Q.10. Compare and contrast the arrangement of elements in Mendeléev’s Periodic Table and the Modern Periodic Table.

Answer:

Mendeleev's periodic table Modern periodic table
Elements are arranged in the increasing order of their atomic masses Elements are arranged in the increasing order of their atomic numbers
Consists of 8 groups Consists of 18 groups
Groups are categorized into subgroups 'a' and 'b' No subdivision of groups.
Noble gases were not grouped since they were not discovered yet Noble gases were grouped together at the end of the table.
There was no place for isotopes Slots for isotopes present according to atomic number

NCERT Class 10 Science Solutions Chapter 5 - Weightage in Board Exams

The Class 10 science chapter 5 exercise solutions on Periodic Classification of Elements have been excluded from the CBSE syllabus for the academic year 2023-24, and as a result, it will not be included in the Class 10 Science board exam. Even though the chapter has been removed, it's worth noting that understanding the fundamental concepts of periodicity and the periodic table can be beneficial for students in comprehending other chapters in the syllabus, such as Chemical Bonding and Chemical Thermodynamics.

For students preparing for the ch 5 science class 10 Science exam, it is advisable to prioritize studying the other chapters that are part of the syllabus. While the chapter on Periodic Classification of Elements can be used as a reference, studying it in detail is not essential for the exam.

Some key points to remember from class 10 Science chapter 5 NCERT solutions:

key points from NCERT Class 10 Science Chapter 5, "Periodic Table":

Periodic Classification: The class 10 science ch 5 question answer introduces the concept of periodic classification of elements, which is the arrangement of elements in order of their atomic number so that elements with similar properties are placed together.

Early Attempts: science chapter 5 class 10 discusses early periodic classification attempts, such as Dobereiner's triads and Newlands' law of octaves, which established the groundwork for organising elements based on their properties.

Mendeleev's Periodic Table: The chapter explores Mendeleev's pioneering work in creating the periodic table. He arranged elements based on their increasing atomic mass and left gaps for undiscovered elements, accurately predicting their properties.

Modern Periodic Table: Students learn about the modern periodic table, which is organized based on atomic numbers. The table consists of 18 vertical columns known as groups and 7 horizontal rows known as periods.

Trends in the Periodic Table: The class 10 chapter 5 science discusses important periodic table trends such as atomic size, ionisation energy, and electronegativity, helping in understanding the periodic behaviour of elements.

Applications: The periodic table serves as a powerful tool for predicting element properties, understanding chemical reactions, and identifying elements with specific characteristics, making it an indispensable resource for scientists and researchers.

The eligibility age criteria for class 10th CBSE is 14 years of age. Since your son will be 15 years of age in 2024, he will be eligible to give the exam.

That totally depends on what you are aiming for. The replacement of marks of additional subjects and the main subject is not like you will get the marks of IT on your Hindi section. It runs like when you calculate your total percentage you have got, you can replace your lowest marks of the main subjects from the marks of the additional subject since CBSE schools goes for the best five marks for the calculation of final percentage of the students.

However, for the admission procedures in different schools after 10th, it depends on the schools to consider the percentage of main five subjects or the best five subjects to admit the student in their schools.
