Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : Anions are larger in size than the parent atom.
Reason : In an anion, the number of protons in the nucleus is less than the number of electrons moving around it.
- a)Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- b)Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- c)Assertion (A) is true but reason (R) is false.
- d)Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?

The size of an anion is larger than its parent atom because anions are formed due to the gain of electrons. When the electrons increase, there are still the same number of protons. The attractive force is thus reduced as there are the same number of protons attracting an increased number of electrons.

Assertion: Anions are larger in size than the parent atom.
Reason: In an anion, the number of protons in the nucleus is less than the number of electrons moving around it.
The correct answer is option 'A': Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
Explanation:
An atom consists of a positively charged nucleus containing protons and neutrons, surrounded by negatively charged electrons. When an atom gains one or more electrons, it becomes negatively charged and forms an anion.
Anions are larger in size than the parent atom:
An atom's size is determined by the arrangement of its electrons. In an anion, the number of electrons increases, resulting in increased electron-electron repulsion. This repulsion pushes the electrons farther apart, causing an increase in the atomic radius or size of the anion. Therefore, anions are larger in size than the parent atom from which they are formed.
In an anion, the number of protons in the nucleus is less than the number of electrons moving around it:
In an anion, the atom gains one or more electrons, resulting in an excess of negative charge. The number of electrons now exceeds the number of protons in the nucleus, leading to a net negative charge. This charge imbalance causes a stronger electron-electron repulsion, leading to the expansion of electron cloud and an increase in the atomic radius.
Therefore, the reason provided correctly explains why anions are larger in size than the parent atom. The increased number of electrons in the anion leads to a stronger electron-electron repulsion and a larger atomic radius. Hence, option 'A' is the correct answer.
Reason: In an anion, the number of protons in the nucleus is less than the number of electrons moving around it.
The correct answer is option 'A': Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
