Answer 1

Answer #1

Effective nuclear charge is the charge felt by an electron from the nucleus. If the electron is far away from the nucleus, then it's effective nuclear charge is less and vice versa.

The effective nuclear charge decreases down the group and it increase along the period.

Therefore, the order is Cs<Ba<K<Li

Lithium has highest effective nuclear charge while Cesium has Lowest effective nuclear charge.
