Consider the following ground-state electronic configurations . Which atom has the lowest first ionization energy? A) [Ne] 3s²3p⁵ B) [Ne] 3s²3p³ C) [Ne] 3s²3p¹ D) [Ne] 3s²3p⁴

Question

Quizplus · Accepted Answer

The lowest first ionization energy corresponds to the atom with the most stable electron configuration, which is the one with a fully filled subshell. In this case, option C has a fully filled 2p subshell with two electrons in the 2s subshell as well, which makes it the most stable configuration and the atom with the lowest first ionization energy.
