Solution

The correct option is B decreases
As nuclear charge increases, the force of attraction also increases which holds the electrons tightly. Therefore the atomic size decreases.

Q. Assertion :Atomic size decreases in a period due to increase of atomic number. Reason: The nuclear charge is increasing and size of valence shell remains same as we move from left to right. Hence, in any period, the atomic size of the element decreases from left to right.

Q. The amount of energy released when an atom in the gaseous state accepts an electron to form an anion. factor which affect electron affinity are: atomic size and Nuclear charge. As atomic radii increases, electron affinity increase. As nuclear charge increase, electron affinity increase. it decrease down a group and increases across a period. Explain.

Assertion: The atomic radius decreases as we move from left to right in a period.

Reason: Effective nuclear charge increases across the period from left to right.

On moving across a period, the atomic size decreases and nuclear charge increases and therefore the force of attraction exerted by the nucleus on the electron in the outermost shell increases.
The first ionization potentials (in eV) of As and Se atoms, respectively, are:

Q. Assertion :The size decreases as

P b > {P b}^{2 +} > {P b}^{4 +}

. Reason: The nuclear charge increases,i.e., the force of attraction towards nucleus increases.
