Question

nuclear charge increases electro positivity​

Answer 1

Answer:

Ok..

But the question is incomplete...

Answer 2

Answer:

You could put it this way: the nucleus attracts the electron more if it has a high effective nuclear charge. ... Thus an electronegative atom/ion/etc "gains more energy" when it pulls an electron towards it. And the reason it "gains more energy" is because it has high effective nuclear charge.
