Answer :
Answer: 1
Fluorine is in group 7, meaning that it has 7 valence shell electrons and to fulfill the octet rule it can only obtain 1 more electron.
When bonding the last lone pair for each of the two fluorine atoms together you create a total of two electrons shared between each.
Therefore you get a total of 8 valence shell electrons.
Remember: when you have 8 valence shell electrons you have obtained an octet
In other words...
8 valence shell electrons = satisfied octet rule
