chemical properties of metal and non metals​

Answer 1

Answer:

Explanation:

Chemical Properties of Nonmetals

In the chemical properties of metals and nonmetals, we will now see the chemical properties of nonmetals

1.Nonmetals are poor conductors of heat and electricity. Graphite and Gas carbon are exceptions.

2.Unlike metals, nonmetals aren’t malleable and ductile.

3.Nonmetals react more with metals than with nonmetals.

4.Usually, nonmetals react with other nonmetals in high temperature.

5.Most nonmetals do not react with air in room temperature.

6.White phosphorus is the only nonmetal that reacts with air to form its oxide by burning.

7.Usually, nonmetals do not react with water. Except for Chlorine, chlorine dissolves in water to form an acidic solution.

Chemical Properties of metals

The chemical properties of Metals and Nonmetals are described below. Let us start with the chemical properties of metals.

1.The density of metals is usually high.

2.Metals are malleable and ductile.

3.Metals form an alloy with other metals or non – metals.

4.Some metals react with air and corrode. For e.g. Iron.

5.Metals are good conductors of heat and electricity. Lead is an exception.

6.Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state.

7.Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen.

Answer 2

Answer:

chemical properties of metals

a) metals combine with oxygen to from basic oxide.

Na + O2 - Na 2O

b) metals react with acid to form hydrogen gas and metal salts.

Znt H2 So4 - Zn SO4 + H2

C) some of the metal react with water.

Mg + H2o - Mg CoH ) 2 + H2
