Which element would most likely bond with lithium and form an ionic compound?

Ionic bonding is the type of bond that is made between a nonmetal and a metal. In this type of union, one of the elements yields electrons and the other accepts electrons.

In this case, the metal is Lithium, we need a nonmetal to complete the union. (Don't know if you need this or anything but here you go)

Beryllium is a metal.

Calcium is a metal.

Fluoride is a nonmetal.

Sodium is a metal.

After the analysis, we conclude that the correct answer is Fluoride since it is the only one that is a nonmetal.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
