What are the key differences between metals and nonmetals?

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.

Can you give me some examples of each?

Sure! Examples of metals include iron, gold, and aluminum. Nonmetals include oxygen, sulfur, and chlorine.

How do their physical properties differ?

Metals have high melting points and densities, while nonmetals generally have lower melting points and are less dense.

What about their chemical properties?

Metals tend to lose electrons and form positive ions, whereas nonmetals usually gain electrons to form negative ions.
