Question

chemical properties of metal and nonmetal​

Answer 1

Answer:

Non metals have more than 4 electrons in their valence shell. So they can gain electrons easily. These elements and those to the right of them are nonmetals. Elements just to the left of the line may be termed metalloids or semimetals and have properties intermediate between those of the metals and nonmetals.

Explanation:

Answer 2

The chemical properties of Metals are described below.

• The density of metals is usually high.
• Metals are malleable and ductile.
• Metals form an alloy with other metals or non – metals.
• Some metals react with air and corrode. For e.g. Iron.
• Metals are good conductors of heat and electricity. Lead is an exception.

In the chemical properties of nonmetals described below:

• Nonmetals are poor conductors of heat and electricity. Graphite and Gas carbon are exceptions.
• Unlike metals, nonmetals aren’t malleable and ductile.
• Nonmetals react more with metals than with nonmetals.
• Usually, nonmetals react with other nonmetals in high temperature.
• Most nonmetals do not react with air in room temperature.
