Question

(b) Discuss the variation of effective
nuclear charge in periodic table.​

Answer 1

Answer:

The periodic table tendency for effective nuclear charge:

Increase across a period (due to increasing nuclear charge with no accompanying increase in shielding effect).

Decrease down a group (although nuclear charge increases down a group, shielding effect more than counters its effect).

Answer 2

Increase across a period (due to increasing nuclear charge with no accompaning increase in shielding effect). Decrease down a group (although nuclear charge increases down a group shielding effect more than counters its effect.
