What is an atom? a. it is a property of material b. it is specification of any material c. it the part of a substance d. it is a grain boundary

Out of the multiple options provided,

option (c) it is the part of a substance

is correct

Explanation:

An atom is basically the smallest particle of matter or we can call it as building block of matter. It is as a brick to the wall or a cell to the body.

Matter is build up of a large number of these atoms. Atoms carbon(C), hydrogen(H), oxygen(O) combines to form molecules such as carbon dioxide(), water(), methane(), etc and then these molecules combines to form a substance.

It cannot be property, neither can it be specification of any material as these two characterizes the material and it can't be grain boundary for sure as grain boundary is the interface between two grain or crystal particles.

This shows that the smallest unit of matter is atom and it is the part of a substance
