Question

what is the difference between metals and non metals
both physical and chemical properties

​

Answer 1

Answer:

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.

Answer 2

Answer:

Physical properties of metal:

1. Hardness

2. Lustre

3. Malleability

4. Ductility

5. Good conductor of heat

6. Good conductor of electricity

7. High density and high melting point

8. sonorous

Physical properties of non metal

1. it exist as solid, liquid or gases.

2. it is not so hard .

3. dull or lusterless in appearance execpt, iodine and diamond.

4. neither malleable nor ductile

5. bad conductors of heat.

6. bad conductors of electricity.

7. not sonorous as they do not produce any sound on being hit.

8. low melting and boiling points.

DIAMOND and GRAPHITE both are made of carbon but they differ in their PHYSICAL PROPERTIES. They are called ALLOTROPES OF CARBON .

CHEMICAL PROPERTIES OF METALS AND NON - METALS

1. Reaction with oxygen

2. Reaction with water

3. Reaction with acids

4. Reaction with bases
