Cations: Lose electrons, more e- attraction
Anions: Gain electrons, more e- / e- repulsion
ion with highest possible charge will be the smallest. this is because z eff is the smallest.
two same elements have same Z eff.
ionization energy is directly proportional to Z eff. Inversely proportional to the radius of species.
Z effect. Electronegativity Ionization energy
Ionization Energy changes every electron lost because the proton to electron pull increases. Z eff remains same.
changes drastically if val
