Question

Plzzz help me friends... I am really confused with this..

Answer 1

Answer:

option B will be the answer

Explanation:

Because,

as we take atomic size

down the group number of shells increases so

atomic size increases and

in the period as number of electrons increases the effective

nuclear charge increases. so,the atom shrinks and atomic size

decreases.

as we consider ionization enthalpy,

down the group as atomic size increases the effective

nuclear charge decreases.so,ionization enthalpy decreases and

in the periods it's vice versa
