Answer:
Matter around us is grouped in two subgroups.
Explanation:
The two subgroups are:
PURE SUBSTANCES
These are divided into two groups:
ELEMENTS are the objects made up of same kind of atoms.
Eg iron
COMPOUNDS are the objects made up of different kinds of atoms but in a definite ratio.
Eg water
IMPURE SUBSTANCES OR MIXTURES
These are the substances which made up of different kinds of atoms but not in a fixed ratio.
These are divided into two groups:
HOMOGENEOUS MIXTURES are the mixtures which cannot be separated by physical means but can be by chemical means.
HETEROGENEOUS MIXTURES are the mixtures which can be separated by both physical and chemical means.
