Another way to prevent getting this page in the future is to use Privacy Pass. The physical properties of metalloids tend to be metallic, but their chemical properties tend to be non-metallic. They are soft solids, except diamond which is the hardest substance known. Physical Properties: We generally look for a metal when we need a strong material. Following are the important chemical reactions of non-metals. Metals react with water differently to produce oxides and hydroxide. The metals and non-metals differ in their properties. Non – metals: Chlorine, Nitrogen, Hydrogen, Oxygen, Sulphur etc.Apart from metals and non-metals some elements show properties of both metals and non – metals, e.g. Non-metals are used in small quantities but are very vital in daily life. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. 2. Copper is used in making electric wires, gold is used to make jewellery, stainless steel is used to make pots, pans, etc Sodium and potassium are exceptions in this case as they can be cut by a knife.
