Final answer:

Metals, semimetals, and nonmetals can be classified based on their properties on the periodic table.


Explanation:

When classifying elements as metal, semimetal (or metalloid), or nonmetal, you can refer to their properties on the periodic table. Metals are shiny, good conductors of heat and electricity, and malleable. Nonmetals are dull, poor conductors, and brittle. Semimetals exhibit properties between metals and nonmetals.
