Abstract
IN a recent article Dash1 has emphasized how three successive ionization potentials Ip, IP+1, Ip+2 in an isoelectronic series of atoms give a constant second difference which is equal to twice the Rydberg constant R divided by the square of the principal quantum number n of the electron being ionized, thus:
