Question

Explain what happens to effective nuclear charge on moving down the group in the periodic table? Give your views on why it happens so? Does it Decreases or Increases?​

Answer 1

Answer:

In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. ... Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital.
