Trends in Zeff with Multiple Ionization
Phosphorous
Experimental Observation of the Atomic properties of various charge states of
Phosphorous Atoms tells us that the effective nuclear charge increases with charge
but less quickly than we would expect because of the incomplete shielding of
electrons within the same shell.
