Q. Three atoms have the following electron configurations respectively:
(i) ${1s}^2{2s}^2{2p}^6{3s}^2{3p}^1$
(ii) ${1s}^2{2s}^2{2p}^6{3s}^2{3p}^5$
(iii) ${1s}^2{2s}^2{2p}^6{3s}^2{3p}^6{4s}^1$
(a) Which of the three has the largest ${\left(IE\right)}_1$?
(b) Which has the largest ${\left(IE\right)}_4$?
Write your answer as a two digit number.
Ex - If answer for a & b is 3 & 2 respectively, answer as 32.
