It sinks in air because it has a high density as is therefore often found in the basements of homes, particularly in areas where with a lot of shale and boulders in the soil. Radon results from the radioactive decay of radium in the soil, and it further decays to produce radioactive daughters including polonium and lead.

The element is a high-melting, silver-white metal which is the first member of the alkaline earth metals. It is not abundant in the environment and occurs mainly in the mineral beryl with aluminum and silicon.

It covers the classification of metals based on physical properties such as conductivity and malleability. Key points include gold's value in jewelry for its softness, copper's role in electrical conduction, and the toxicity of mercury, the only liquid metal at room temperature, which has fallen out of common use.

It explores various solute-solvent combinations, including gas-gas, solid-solid, and liquid-liquid solutions, emphasizing that while water is a key solvent, other combinations are also present. The chapter raises concerns about mercury's toxicity in dental amalgam despite its effectiveness in binding metals.
