Question

write three differences between metals and nonmetals of chemical properties​

Answer 1

metals react with oxygen to form metallic oxides.

nonmetals react with oxygen to form nonmetallic oxides.

metals react with water and nonmetals do not

Answer 2

Answer:

Explanation: Metal

1. Metals are electropositive.

2. They react with oxygen to form basic oxides.

3. These have ionic bonds.

4. They react with water to form oxides and hydroxides. Some metals react with cold water, some with hot water, and some with steam.

5. They react with dilute acids to form a salt and evolve

hydrogen gas. However, Cu, Ag, Au, Pt, Hg do not react.

6. They react with the salt solution of metals. Depending on their reactivity, displacement reaction can occur.

7. They act as reducing agents (as they can easily lose

electrons).

 Non-metal

1. Non-metals are electronegative.

2. They react with oxygen to form acidic or neutral oxides.

3. These have covalent bonds.

4.They do not react with water.

5. They do not react with dilute acids. These are not capable of replacing hydrogen.

6. These react with the salt solution of

non-metals.

7. These act as oxidising agents .
