answered-by-expert Expert Answer
  • A molecule is a group of two or more atoms chemically bonded together. A molecule is the smallest particle of an element or a compound which has properties of the element or the compound and can exist in a free state.
  • Molecules can be formed either by the combination of atoms of the same element or of different elements.
  • Thus, there are two types of molecules — molecules of elements (Example: O2, H2, Cl2, N2) and molecules of compounds (Example H2O, NH3).
