The solid non metals are amorphous. Unlike metals the non metal solid do not usually form a regular crystal shape. The solid non metals are generally soft and easily broken into pieces.

However there are exceptions. Diamonds are a from of the nonmetal Carbon that forms very hard crystals.

There are many non metal gases such as all of the group VIII A or inert gases, Oxygen, Nitrogen, Florine, and Chlorine.

More distinctive than the physical properties of the non metals are their chemical properties.
