WebThe number of protons and neutrons combine to give us the mass number of an atom. It is represented using the letter ‘A.’. As both protons and neutrons are present in the nucleus of an atom, they are together called nucleons. For example, an atom of carbon has 6 protons and 6 neutrons. Thus, its mass number is 12. WebThe following electrons can also be used to define valence: Number of electrons in the last/valence shell of a free atom - Number of electrons on an atom in a non-bonded molecule. As a result, the formula for valency definition in chemistry is Valence or Valency = Number of bonds created + Formal charge of the atom.
