Class 9 Chemistry Atoms and Molecules Molecules

Molecules

We all know that bricks are the basic building blocks of a building. The bricks cannot exist independently. The bricks are used to make small rooms that together constitute the entire building. The rooms can be regarded as molecules that are composed of bricks and together build up the entire building.

Similarly in most of the elements atoms do not exist independently. They exist as molecules that aggregates in large numbers to form the matter.

Molecules refers to the cluster of two or more atoms chemically bonded together and tightly held together by attractive forces. It can be defined as the tiniest particle of an element or compound proficient of an independent existence and shows all the properties of that substance.
