notes
Classification of Matter:-
Based on the chemical composition of various substances.
Elements:
- It is the simplest form of the matter.
- The smallest unit of an element is known as an atom.
- The total number of known elements is 118 out of which 98 elements occur naturally and 20 are formed by artificial transmutation.
- Examples: Na, K, Mg. Al, Si, P, C, F, Br etc.
Compound:
- It is a non-elemental pure compound.
- Formed by a chemical combination of two or more atoms of different elements in a fixed ratio.
- Examples: H2O, CO2, C6H12O6 etc.
Mixture:
- Formed by the physical combination of two or more pure substances in any ratio.
- The chemical identity of the pure components remains maintained in mixtures.
- Homogeneous mixtures are those whose composition for each part remains constant.
- For example, Aqueous and gaseous solutions.
- Heterogeneous mixtures are those whose composition may vary for each and every part. For example, Soil and concrete mixtures.
