WebHow can they figure out the atomic mass of the unknown elements. ... There was no periodic increase in the atomic mass between two elements. so it is not easy to predict how many elements can come between two elements . For example, the difference of atomic mass between element A and B =2.5u, 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.
