The chemical properties of metals include the reaction of metals with different substances such as oxygen, water, acids, bases, etc. Non metals do not have lustre some have a dull luster. When the non-metals are exposed to oxygen, they form their respective acidic oxides. 1. Non-metals tend to gain or accept valence electrons. Non-metals are also transparent. Chemical Properties of Metals Most metals have 3 or less valence electrons and therefore are likely to lose these electrons in chemical bonds. Non-metals usually possess about 4 to 8 electrons in their valence shells. 2. They mostly have a very high melting point. Unlike metals, nonmetals aren't malleable and ductile.

Some chemical properties of non-metals are listed below. 1a) Physical properties of metals :- Metals are solids. The important physical properties of the metals are density, color, size and shape (dimensions), specific gravity, porosity, luster etc. Non metals which are solids are brittle (diamond is the hardest). Q.4. Non-metals are not lustrous which means they are not shiny. Mass per unit volume is called as density. Physical Properties of Non-metals In contrast to metals, non-metals are not known for strength. E.g. The Periodic Table contains over 100 different elements; They can be divided into two broad types: metals and non-metals; Most of the elements are metals and a small number of elements display properties of both types These elements are called metalloids or semimetals The metallic character diminishes moving left to right across the Periodic Table.
