Does atomic size increases monoatomically with increase in atomic mass

1.	Does atomic size increases monoatomically with increase in atomic mass? If not, can you guess why not?
Answer» No, it does not increase monoatomaically with the increase in atomic mass. It is because of the fact that the size of atom is due to the electron shells around the nucleus. When the mass of atom increases, it means the number of nucleons in the nucleus of the atom has increased. As a result atomic number may increase. However, the increase in the number of electrons (atomic number) may be only into a shell of the atom, Thus, the size of the atom may not increase.
