2 Easy Definitions of Molecules | Chemistry

In this animated lecture, I will teach you 2 the definitions of a molecule in chemistry.

Q: Define a molecule?
Ans: The easy definition of a molecule is that "when two or more atoms combine together chemically, they form a molecule".
For example, when two hydrogen atoms and one oxygen atom combine together chemically, they form a molecule of water.

Q: What is the second definition of a molecule?
Ans: The second definition of a molecule is that   "The smallest unit of matter which can exist free or independent in nature is called molecule".
For example, consider the single atom of Neon. It can exist free in nature. So, it is a molecule.

Also, you will learn about:
1) Mono-atomic molecules
2) Di-atomic molecules
3) Tri-atomic molecules
4) Poly-atomic molecules

To learn more about the definition of molecules, watch this lecture till the end.
