Element Groups and Properties

Metals, Nonmetals, and Metalloids

Use different colors or shading to indicate the location of metals, nonmetals, and

metalloids.

Compare and contrast metals, nonmetals, and metalloids in terms of their properties.

 Metals are generally solid (except Hg), conductive of heat and electricity,

malleable, ductile, shiny, and form cations. Nonmetals are gases or dull,

brittle solids, generally show poor conductivity, ductility, and malleability

and generally form anions. Metalloids have properties in between the two.

Why do metals tend to form cations, while nonmetals form anions?

 Metals generally form cations because they have low numbers of valence

electrons. Nonmetals have more and would gain an octet easier by adding

than losing.

Identify each of the following as being a Metal (M), Nonmetal (NM) or Metalloid (MO).
