[Free Registration/Login may be required to access all resource tools.] Describes the properties of non-metals and uses of non-metals

A covalent bond is formed between non metal atoms, which combine together by sharing electrons. Covalent compounds have no free electrons and no ions so they don't conduct electricity.

This section of the lesson module focuses on covalent bonds, which are formed between non-metal atoms that share a pair of electrons. It includes links to a video and a test. Other types of chemical bonds are covered elsewhere in the...

The following tutorial explains the three main types of elements, including metals, non-metals and metalloids.
