The electron configuration 1s²2s²2p⁶ applies to all of the following species except: A)Ne B)F⁻ C)O²⁻ D)Na⁺ E)Ca²⁺

Question

Quizplus · Accepted Answer

The electron configuration given corresponds to a noble gas, neon (Ne), with a full outer shell (1s2 2s2 2p6). Options A, B, C, and D all have electron configurations that would result in a neon-like (Ne) noble gas configuration after gaining or losing electrons to achieve a full outer shell. Option E, calcium with a 2+ charge (Ca2+), would have an electron configuration ending in 2s2 2p6, which matches the given configuration, but it starts from a different base configuration (Ca's ground state is [Ar] 4s2) than the other options, which are closer to neon in the periodic table.
