al chem ! atomic structure

我唔明點解書成日都話

when effective nuclear charge increase, atomic radius decrease, therefore, electron become closer to nucleus and it is more lose an electron.

但唔係when effective nuclear charge increase, the electron experience stronger nuclear attraction 我既concept 有錯嗎? 點解成日提到radius, 有咩關係呢?
