Question

Metals and nonmetals chemical properties std 8

Answer 1

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

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.Generally, metals are in a solid state at room temperature.
In the chemical properties of metals and nonmetals, we will now see the chemical properties of nonmetals

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.White phosphorus is the only nonmetal that reacts with air to form its oxide by burning.Usually, nonmetals do not react with water. Except for Chlorine, chlorine dissolves in water to form an acidic solution.
