About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
