3.3-Covalent Bonds - 1

Nonmetal atoms share valence electrons to form ____ that hold atoms together.

• ionic bonds

• Covalent bonds

• metallic bond

A molecule is best defined as:

• a charged particle

• a mixture of atoms

• a neutral group of atoms held together by covalent bonds

• a solid lattice of ions

Covalent bonds form when atomic orbitals:
