In this video I’ve taught you about atomic number and mass number. These two, atomic number and mass number are very basic things to learn in chemistry. Atomic number basically means that the number of protons in this atom but mass number means the mass of the whole nucleus, which includes protons and Neutrons only. Atomic number and mass number are important to learn in chemistry.
