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.

Question:
<em>What effects does the concentration of reactants have on the rate of a reaction?</em>
Answer:
<em>Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.</em>
<em>Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. ... When concentrations are already high, a limit is often reached where increasing the concentration has little effect on the rate of reaction.</em>
