5. (5-6) State and explain the number of valence electrons in F

Simply F stands for Fluorine

Its atomic number is 9 .

It consists of 2 electrons on k shell and 7 on L shell .

In order to come in octate state it has to gain one electron

Hence, its valence electrons are 7.

Thank u I have just tried it It may be right in some extent and may be wrong too

answer; i believe the correct answer is (solid gold);
