Which of the following atoms has the lowest ionization potential ?

A

`._(7)^(14)N`

B

`._(55)^(133)Cs`

C

`._(18)^(40)Ar`

D

`._(8)^(16)O`

Text Solution

Verified by Experts

The correct Answer is:
B
Ionization potential will be lowest for the atom in which the electrons are the farthest from the nucleus. So, the atom with the largest size will have the electron the farthest from the nuclei, hence to remove the electron from this atom will be easiest. so, the atom with least Ionization potential is `._(55)^(133)Cs`.

Which of the following elements has the lowest ionization potential ?

The energy required to pull the most loosely bound electrons from an atom is known as ionization potential. It is expressed in electron volts. The value of ionization potential depends on three factors :(i) the charge on the nucleus (ii) the atomic radius and (iii) the screening effect of inner electron shells.
