bonds

Metallic bond properties

• do not dissolve in water

• conduct electricity

• bendable and hard solids

• made entirely of metal atoms

Metallic bond valence electrons movement

Free to move about the substance

Network Covalent Properties

• do not dissolve in water water

• do not conduct electricity

• extremely hard solids

• made entirely of nonmetal and metalloid atoms

Network covalent valence electrons movement

Valence electrons connect atoms with each other in all directions, like a grid or network.

Ionic bond properties

• dissolve in water

• conduct electricity with dissolved

• brittle solids

• made of metal and nonmetal atoms combined

Ionic bond valence electrons movement

Metal atoms “give up” their valence electrons to nonmetal atoms.

Molecular covalent bond properties

• some dissolve in water, some do not

• do not conduct electricity

• some are liquids or gases

• made entirely of nonmetal atoms

Molecular covalent bond valence electrons movement

Valence electrons are shared between some atoms. This creates small stable units within the substance.
