1
A fluorine atom has seven unshared electrons in its outer most shell (valence shell).
It is in Group 7 on the Periodic table which means it already has 7in its outer shell. The shell needs 8 to be complete so fluorine requires 1 more electron which it gains through ionic or covalent bonding.
Calcium has two electrons in the outer shell.
Vanadium has on the outer shell two electrons.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
8 electrons on the outer shell
7 electrons
Fluorine has 9 in total. 7 in the outermost shell
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
