Answer:
Anything that occupies space and has mass is called matter
Composition of matter
A molecule is the smaller particle of an substance which can independently exist in nature.
A molecule may be made up of even smaller particles called atoms. A molecule may contain one or more atoms bonded together.
FOR EXAMPLE
A water molecule consists of two atoms of hydrogen and one atom of oxygen bonded together. However, a single atom cannot exist independently in nature
