Question

Write the full ground state electron configuration of f+.

Answer 1

Answer:- $1s^22s^22p^4$ .

Explanation:- Atomic number for fluorine(F) is 9 and it's electron configuration is $1s^22s^22p^5$ . $F^+$ is formed when F loses one electron from it's valence shell.

$F\rightarrow F^++1e^-$

Second shell is the valence shell for fluorine and so it loses one electron from 2p to form  $F^+$  and the electron configuration of the ion becomes $1s^22s^22p^4$ .
