Answer 2

ATOM:-

What is an atom? – an atom is the smallest possible amount associated with a chemical element. For example, an atom of gold can be called as the smallest quantity of gold you can feasibly have. The word ‘small’ literally points out to nanoscopically tiny! An atom is thousands of times smaller than a human hair.

Hence, there is no chance you can see one without the help of a supremely powerful electron microscope. If you rip apart a variety of things, it would be revealed that all matter present around us is formed from different types of atoms. For example, living things are usually made from atoms hydrogen, carbon and oxygen.
