Metals refers to the natural elements that are hard, shiny, opaque and dense. Non-metals implies those chemical substances that are soft, non-shiny, transparent and brittle. Most metals are hard, except sodium. Most non-metals are soft, except diamond.

Metals usually have a metallic or shiny appearance. Nonmetals are usually have a dull luster (or you can say they lack luster). Most are shiny (metallic luster), malleable, ductile, high density and high melting point, and good conductors of heat and electricity.

Metallic Minerals are composed of one or more metallic elements whereas non-metallic minerals do not contain any metal elements instead they consist of chemical elements that usually don't feature the properties or characteristics of metals.

The elements can also be divided into two main groups, the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties. There are some elements that show some, but not all, of the metallic properties.

Chemical Properties of Nonmetals Nonmetals are poor conductors of heat and electricity. ... Unlike metals, nonmetals aren't malleable and ductile. Nonmetals react more with metals than with nonmetals. Usually, nonmetals react with other nonmetals in high temperature.

['Nickel is silvery-white, hard, malleable, and ductile metal.', 'It is a good conductor of heat and electricity.', 'It is bivalent, that is it has a valency of two.', 'The metal dissolves slowly in dilute acids.', "It's melting point is 1453 °C and boiling point is 2913 °C."]

metals are ductile ,malleable, luster,whereas nonmetals are not. Metals have a tendency to lose electrons while non metals have the tendency to gain electrons. ... The main difference between metal and non-metal is that metal give electron to another atom or compound while non metal accept electron from other substances.

The nonmetals include the nonmetals element group, plus the halogens, and noble gases. Properties of nonmetals include: Dull, not shiny. Poor conductor of heat.

They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids.

Metals are dense, shiny, good conductors of heat and electricity, and easily lose electrons in chemical reactions. Nonmetals are not dense, dull, do not conduct heat and electricity, and tend to gain electrons. Metalloids are elements that have properties of both metals and nonmetals.
