Answer #1

Solution.

The electronic configuration of neutral fluorine atom is 1s22s22p5;

F- ion has one more electron 1s22s22p6

F+ ion has one less electron 1s22s22p4

The MO diagram of the F2 formation resulting from interation between F- and F+ given below:

The bond order can be calculated as

The number bonding is 10, and number of antibonding is 8; the bond order is (10-8)/2 = 1. Bond order is the number of chemical bonds between a pair of atoms and indicates the stability of a bond.  If the bond order is greater than 0, the molecule is stable. So, the bond between F- with F+ is stable.
