Question

What is the ground-state electron configuration of the fluoride ion F−? Express your answer in condensed form, in order of increasing orbital energy. For example, [He]2s22p2 should be entered as [He]2s^22p^2 .

Answer 1

Answer:

[He]2p6

Explanation:

Fluorine has an atomoc number of 9 which means 9 electrons with the electon configuration:[He]2p5,However,when it becomes Fluoride ion,it gains one electron to complete its outermost shell to obtain an octet configuration and becomes [He]2p6.
