While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well.
If you recall from earlier lessons,
Atomic number (Z) is the number of protons in the nucleus of an atom. It is also equal to the number of electrons since the atom is electrically neutral.
Mass number (A) is the total number of neutrons and protons present in the nucleus of an atom.
formula to find mass number present in an element
The mass number of elements in most of the cases is approximately twice the value of their atomic number. This indicates that the neutron-proton (n/p) ratio of such elements is close to unity. However, it is not so in case of some heavy metals.
