Ionic, Covalent, and Metallic Bonds

Why do bonds form?

• To fill the valence shell of electrons for the elements involved
• to release energy stored in the bonds
• because whenever you mix two chemicals, there will be a reaction
• because of attraction

A solid substance is an excellent conductor of electricity. The chemical bonds in this substance are most likely?

• ionic, because the valence electrons are shared between atoms
• covalent, because the valence electrons are mobile
• metallic, because the valence electrons are stationary
