Common bonding partners for lithium?

Question

What are the most common bonding partners for lithium?

Answer 1

Electron configurations of
lithium and fluorine.

Lithium has one electron in its outer shell, held rather loosely because the ionization energy is low.

Fluorine carries 7 electrons in its outer shell. When one electron moves from lithium to fluorine, each ion acquires the noble gas configuration.

The bonding energy from the electrostatic attraction of the two oppositely-charged ions has a large enough negative value that the overall bonded state energy is lower than the unbonded state
