What is Effective Nuclear Charge?
Effective Nuclear Charge is the net positive nuclear charge experienced by a valence electron orbiting the positively charged nucleus in an atom. Effective nuclear charge is redcued by:
-increased distance between nucleus and subject electron
-increased electron shielding(more electrons between subject electron and nucleus)
-reduced number of protons in nucleus(reducing overall positive charge in nucleus)
