How can valence electrons be used to predict the type of compounds formed?

Valence electrons are the electrons in the outermost shell. Those are the electrons on an atom that can be gained or lost in a chemical reaction.
Elements that are left on the periodic table have relatively few valence electrons, and can form ions more easily by losing their valence electrons to form positively charged cations.
Nonmetals are further to the right on the periodic table, so they gain electrons relatively easily and lose them with difficulty.

Metallic bonding occurs between atoms of

Pavel [41]

Answer:

Metallic bonding occurs when you have a metal in the solid or liquid state. The s and p valence electrons of metals are loosely held. They leave their “own” metal atoms. This forms a "sea" of electrons that surrounds the metal cations.
