WebJan 30, 2024 · You might have expected a much larger ionization energy in sodium, but offsetting the nuclear charge is a greater distance from the nucleus and more screening. Li: 1s 2 2s 1: 1st I.E. = 519 kJ mol-1: Na: 1s 2 2s 2 2p 6 3s 1: ... The sodium's outer electron is in the third level, and is screened from the 11 protons in the nucleus by a total of ... WebAbout Transcript Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan.
