Atoms and Molecules - what is the difference??

This video tutorial explains the differences between atoms and molecules. Atoms are the smallest units of matter, consisting of protons, neutrons, and electrons, and retain the properties of an element. Molecules form when two or more atoms bond together to achieve stability. The video provides examples such as O2 and H2O to illustrate these concepts, emphasizing that atoms are the building blocks of molecules.
