Well, as you know, an atom consists of electrons, protons and neutrons. The number of electrons in the outermost shell gives us the valency of the atom. Similarly, the number of protons and neutrons are associated with the atomic number and mass number of the atom. Recommended Videos Introdu...

It is convenient to describe the composition of an atom in terms of the number of protons and neutrons in its nucleus (Figure 1 ). The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to ...
