Question 11

Metallic Solids

Answer 11

Metallic atoms with very loose electrons for a lattice of nuclei held together by a sea of electrons, or metallic bonds.

Question 12

Molecular Solids

Answer 12

Nonmetal atoms form molecules with covalent bonds. The molecules are held together in a solid by intermolecular forces of attraction.

Question 13

Ionic Solids

Answer 13

Metal and nonmetal atoms form a lattice of alternating positive and negative ions held together by ionic bonds.

Question 14

Network Covalent Solids

Answer 14

Nonmetal atoms form a lattice structure held together with covalent bonds.
