Tungsten is used for the filaments of light bulbs because it glows white-hot without melting. What's most noticeable about this metal is how lightweight, soft, and malleable it is. Mass = total mass of all atoms / atomic number. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Metals react with oxygen to form metal oxides, which are basic in nature, so they have electrovalent or ionic bonds. Liquid metal is composed of alloys with very low melting points that form a liquid eutectic at room temperature. Most of the non-metals are gasses.

When sulphur dioxide reacts with water it forms sulphurous acid. Substance whether solids, liquids, or gases can be metals. Compared with nonmetallic solids, they in general are good conductors of heat and of electricity. The one exception to this is carbon. The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium. A list of ferrous metal properties: 1. Base + Non-metal oxide ⟶ Salt + Water In contrast, except mercury, all metals are solids at room temperature. Before going over the complete list of metals, it is important that we define what is a metal. Nonmetals are plentiful and useful. 4. The following are the general properties of non-metals. Several of the other properties of non-metals result from their atomic sizes. This means that the atoms of non-metals have a strong tendency to attract more electrons than what they would normally have. It is silvery-white metal and shows brilliant luster when fresh. Uses of non-metal. For example, sulfur reacts with oxygen to produce sulfur dioxide. Both loss or gain electrons in chemical reactions Nonmetal or non-metal is a chemical element that does not have the properties of a metal. Therefore, they lack the malleability and ductility exhibited by metals. The fact that so many non-metals exist as liquids or gases means that non-metals generally have relatively low melting and boiling points under normal atmospheric conditions. Some they are even solid at room temperatures like Carbon, sulphur and phosphorus. 1. Non-ferrous Mineral: Those minerals which comprise of some other metal rather than iron is known as a non-ferrous metallic mineral. 3. Ductility is the property of the material to be stretched into wires but non-metals are not ductile except for carbon, as carbon fibres find uses in a wide variety of industries including sports and music equipment. The main metal used to be mercury, but in different applications, gallium-based alloys, which are lower in both their vapour pressure at room temperature and toxicity, are used as a replacement. Some examples from real life; plastics, polymers, wood, glass, composites (sometimes these contain metals) and gases. They are soft, non-lustrous (except iodine) and good insulators of heat and electricity. This means that the atoms of non-metals have a strong tendency to hold on to the electrons that already have. Some gases include hydrogen, helium, oxygen, nitrogen, fluorine, neon, or radon and many more. The oxides of non-metals are acidic or neutral in nature.
