it is because cations are formed by loss of electron and anions are larger because they are formed by the gain of electrons ..... .and cation is that the parent Atom so it is smaller in size

HEY DEAR .
----------------------------------------
Parent atom has more electrons so the effective nuclear charge on each electron is less. Now when a cation is formed electron(s) is/are lost. So the effective nuclear charge or simply put, the attraction of the nucleus towards the electrons increases. So due to greater pull, the nucleus pulls the shells towards it.. there by reducing the size.
