A ​ (a)   bond happens when nonmetals unequally share their electrons. One element holds the electrons a little closer to itself than the other, creating partial charges. A ​ (b)   bond happens when nonmetals share their electrons equally with one another.​ ​ ​

• polar covalent

• nonpolar covalent

• crystal lattice

• ionic
