Describe the properties of a metal, nonmetal, or metalloid.

Metals are generally shiny, malleable, and hard. ... Example non-metal elements are Hydrogen and Carbon. Metalloids share characteristics of both metals and non-metals and are also called semimetals. Metalloids are typically semi-conductors, which means that they both insulate and conduct electricity.

hope this helps!

Explanation:

A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals tend to have relatively high ionization energy, electron affinity, and electronegativity. They gain or share electrons when they react with other elements and chemical compounds.
