Solution

The correct option is A A decrease in the ionization potential
Screening effect of inner electrons will lead to decrease in attraction of outer electrons from the nucleus. Hence there is decrese in ionization potential because it will be easier to remove outermost electron now.

Q. State whether the ionization potential increases or decreases on going down a group.

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 :On moving down the group, ionization enthalpy decreases. Reason: With decrease in size of the atom, the force of attraction between the nucleus and valence electrons decreases.

Assertion and Reason Type

In the following questions, a statement of Assertion $(A)$ followed by a statement of the reason $(R)$ is given. Choose the correct option out of the choices given below each question.

Assertion $(A) :$ Generally, ionization enthalpy increases from left to right in a period.

Reason $(R) :$ When successive electrons are added to the orbitals in the same principal quantum level, the shielding effect of the inner core of electrons does not increase very much to compensate for the increased attraction of the electron to the nucleus.

Q. 2.The ionization potential for the electron in the ground state of hydrogen atom is 13.6 cv. What would be the ionization potential for the electron in the first exicted state of Li2+?
