is the energy required to remove an electoron from an atom or ion
Nuclear charge, atomic redius , electoron sheilding
greater charge + stronger attraction+ higher ionzation energy
a smaller raudis + closer to electorons + higher ionzation energy
the distance from the nucleus to the outermost electron in an atom .
positive charge of the nucleus due to portons .
repulsion between inner and outer electrons reducin gthe effectivw nuclear charge
stronerger attraction = harder to remove electorons = higher energy
closer proximity = strong attraction = higher ionzation energy
greater nuclear charge higher ionzation vs smaller atomic radius higher ionzation
closer electorons = stronger attraction = higher energy
