It is the hardest among naturally occurring substances. They generally form basic oxides. Diamond is an allotrope of Carbon, which is a Non-metal. Chemical Properties of Non-metals: Reaction with Water, Chlorine. 2. PROPERTIES OF METALS AND NON METALS - SlideShare Valency. Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals. Physical properties of non-metals. Non-metals (Complete List) - Definition, Physical & Chemical Properties Answer (1 of 2): I assume you mean "what are the properties of nonmetals." As the name suggests, if metals have common properties, which the nonmetals do not share them. For example, 4K + O 2 2 K 2 O Metal oxides are generally basic in nature but it can also be amphoteric in . Chemical combination, Properties of Metals, Nonmetals & Noble (inert) gases. . There are generally 1, 2 or 3 electrons in the outermost shell of metals. Iron. The molecules of metals in vapour state generally have one atom. A few of the chemical properties of metals are listed below. Silver, Gold, Copper, Aluminium. The density of metals is usually high. For e.g. 7. (shine) Metals are malleable. Metals are Generally hard in nature. Non-metals are less reactive than metals. Metals form an alloy either with other metals or nonmetals. Form acidic oxides: Non-Metal can form acidic oxides when . Non-metals are good insulators, i.e., a poor conductor of electricity. Generally, non-metals do not react with water. The number of the well-known elements up till now is 118 elements, These elements can be classified according to their properties and electronic structure into metals, nonmetals and noble (inert) gases, In the 19th century, Berzelius (1779-1848) was the first scientist . Lustre: Non-metals have dull appearance. For example iodine (I) is soluble in alcohol. Many non-metals like chlorine, sulphur, iodine are very useful for medicinal purposes.
