Answer:

A substance is a matter which has a specific composition and specific properties. Every pure element is a substance. Every pure compound is a substance. Examples of substances: Iron is an element and hence is also a substance. It is a mixture of two substances - sodium chloride and water.

Example:-

A sample of silicon consists of only one type of atom: silicon atoms. Therefore, silicon is a pure substance. Since these silicon atoms are in their simplest form and cannot be broken down any further, the substance, silicon, is also an element. Remember, an easy way to figure out whether or not something is an element is to look for it on the periodic table. Anything represented on the periodic table is an element and is, therefore, a pure substance! Silicon is number 14 on the periodic table and has the symbol Si.
