Question

use five physical properties to compare and contrast metals and non metals .​

Answer 1

Explanation:

physical property of metal

.The physical properties make them useful for many purposes. For e.g. Copper is used in making electric wires, gold is used to make jewellery, stainless steel is used to make pots, pans, etc

.Metals react with nonmetals to form ionic bonds. For e.g. Sodium Chloride (NaCl)

.Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. Copper is used as wiring as it is a good conductor of electricity.

.Metals have high melting points and high boiling points as they have strong metallic bonds.

.All metals are physically lustrous. They have a lustre that makes them shine. Gold is used for jewellery

Physical Properties of Nonmetals

.Nonmetals have high ionization energies.

.They have high electronegativities.

.Nonmetals are insulators which means that they’re poor conductors of electricity.

.They are dull, they do not have lustre like metals.

.Nonmetals are poor conductors of heat. They’re poor therma
