What You Will Learn!
- Physical, Chemical Properties and Uses of Metals and non metals
Description
This Course deals with the Extraction of Metals and Non Metals, Physical and Chemical Properties of Metals and Non Metals and Uses of Metals and Non Metals.The elements which are quite reactive and have a tendency to react with moisture, carbon dioxide, oxygen, sulphur, halogens, etc., are found in combined state. Most of the metals are found in the combined state as minerals.
All the materials around us are made up of chemical elements, which are found in the earth’s crust. Earth is the source of coal, petroleum, graphite, diamond and many other minerals of metals and non-metals. We get various useful things like gasoline, kerosene, wax, coal gas, minerals and rocks in the natural resource, which are made up of many non-metals. These elements occur as minerals and rocks in the earth’s crust. Some of these elements like oxygen, nitrogen and carbon dioxide occur in atmospheric air.
There are more than 119 element known at present 80% of these elements are metals and rest are non – metals. On the basis of their characteristic properties, all of these elements are divided into two main groups : metals and non-metals.
POSITION OF METALS AND NON-METALS IN THE PERIODIC TABLE
The elements which are placed on the left hand side (except hydrogen) and in the center of the periodic table are called metals. Such as sodium, potassium, magnesium, calcium, iron, copper, zinc etc.
