The question is incorrect, the correct question is;

Which of the following ground-state electron configurations represents the atom that has the

lowest first-ionization energy?

a) 1s2

b) 1s22s2

c) 1s22s22p6

d) 1s22s22p63s23p1

e) 1s22s22p63s23p3

The correct ground state configuration that represents the atom that has the lowest first ionization energy is 1s² 2s² 2p⁶ 3s² 3p¹.

The first ionization energy is the energy required to remove an electron from the outermost shell of an atom.

Ionization energy decreases down the group as number of shells increases but increases across the period as nuclear charge increase.

As the number of shells increases, the degree of shielding or screening decreases it easier to remove the outermost electron.

The elements whose ground state electronic configurations were shown are;

Helium - 1s²  

Beryllium - 1s² 2s²  

Neon - 1s² 2s² sp⁶  

Aluminum - 1s² 2s² 2p⁶ 3s² 3p¹    

Phosphorus - 1s² 2s² 2p⁶ 3s² 3p³

Aluminium (1s² 2s² 2p⁶ 3s² 3p¹) is a metal so it has the lowest first ionization energy since metals are highly electropositive.
