how do atoms share more than one pair of electrons?

Explanation:

Step1: Determine valence electrons

Fluorine has 7 valence electrons. In $F_2$, two fluorine atoms share electrons to achieve an octet.

Step2: Find number of shared electrons

Each fluorine atom needs 1 more electron to complete its octet. So, they share 1 pair of electrons.

Answer:

F - F
