Questions
Which of the following atoms has the lowest ionization potential?
a
O 816
b
N 714
c
Cs 55133
d
Ar 1840
detailed solution
Correct option is C
Since the Cs 55133 has larger size among the four atoms gives, thus the electrons present in the outermost orbit will be away from the nucleus and the electrostatic force experienced by electrons due to nucleus will be minimum. Therefore the energy required to liberate electron from outer will be minimum in the case of Cs 55133.Talk to our academic expert!
