Question

what is metal?what is non metal its example ​

Answer 1

Answer:

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires).Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc. Well-known alloys include bronze and steel.

In chemistry, a nonmetal is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Examples of nonmetals include hydrogen, carbon, chlorine, and helium. Properties of nonmetals include a relatively low boiling point, so many nonmetals are gases. Nonmetals are also poor conductors of heat, and solid nonmetals are dull and brittle.

Answer 2

Answer:

★ Metal :- Those solid Metarial which are typically hard, shiny, malleable, fusible and ductile, with good electrical and thermal conductivity is called Metals.

Examples :- Iron, gold, Sliver and aluminium etc.

★ Non Metals :- Those materials which are not metals are called Non Metals.

Examples :- Wood, cotton, paper and Plastic etc.
