Metals and Non-Metals

In this topic, we will learn the various properties of metals and non-metals in detail with their examples. With the use of various activities, we will learn the physical properties of metals and non-metals.

This topic explains that highly reactive metals react with to form metal hydroxides and gas. They form basic oxides on reaction with gas. They react with acids to form salt and gas. More reactive metals displace less reactive metals from their salt solutions.

This topic explains the reactions of metals with non-metals. We will also go through the chemical equations of a metal reacting with a non-metal in detail.

This topic describes minerals as the elements or their compounds which are obtained directly from the earth’s crust. Metals can be extracted from their ores. The extraction of metals from their ores involves concentration, conversion into oxide, reduction and refining.

This topic explains that oxidation of the surface of a metal due to the action of atmospheric oxygen and water is known as corrosion. Corrosion of iron is called rusting. It can be prevented by galvanisation, chrome plating, alloy formation and electroplating.

This topic talks about the chemical properties of non-metals. They exhibit low malleability and ductility. Unlike metals, non-metals react highly when they come in contact with metals.
