Answer 2

Non- Metals can be simply defined as elements which are not metals.

Explanation:

• Non-metals lack all of the characteristics of metals. Heat and electricity are well-insulated by them. Gases and liquids are the most common types.
• Some non-metals are found as gases, others as solids, and one is found as a liquid under normal temperature and pressure. All metals, with the exception of mercury, are solids at room temperature. Due to the large number of non-metals that exist as liquids or gases, non-metals have low melting and boiling points under normal atmospheric conditions.
• Non-metals have a tendency to be brittle in their solid state. As a result, they lack the malleability and ductility that metals have.
• The elements which are non metals are: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine, Carbon Sulphur, Phosphorus, and Silicon
