ChemistryChemical Bonding and Molecular StructureJEE Main

It is thought that atoms combine with each other such that the outermost orbit acquires a stable configuration of 8 electrons. If stability were attained with 6 electrons rather than with 8, what would be the formula of the stable fluoride ion?

Answer: (B)

Solution

Fluorine has 7 electrons in its valence shell. If a stable outer shell required only 6 electrons (instead of 8), fluorine would need to lose 1 electron
