Covalent bonding - a type of bonding in which electrons are shared between two atoms

• It's different from ionic bonding, in which electrons are transferred

Covalent Bonding

• Ions don't form because atoms do not lose or gain electrons

• Covalent bonds form because electrons are shared

Covalent Bonding

• Covalent bonding happens between nonmetal atoms

• It also forms molecules instead of crystals

• Molecules have a definite size and shape instead of continuing in all three dimensions

Molecules, Not Crystals
