Metals and Non Metals

Before reading metal and non metal we must understand what is element and what is compound.

Element - an element is a pure substance which cannot be broken down further. eg - Gold, silver, oxygen, carbon etc.

Compound - is a substance made of two or more element. e.g. - water, carbon dioxide etc.

Before classifying material as metal or non metal, first think it is an element or a compound. In this chapter you have to classify only element as metal or non metal. so when anyone ask you Tree is metal or non metal, so just think can this be broken down further - if yes (tree is made of carbon) then just say it is a compound. It is a non-metal.

Materials can be classified into two types -

1. Metals and
2. Non-Metals

We can define Metals and Non-metals on the basis of its properties.
