Question

The effective nuclear charge decreses wit increase in which quantum number

Answer 1

Answer:

Step-by-step explanation:

The effective nuclear charge ( Zeff ) increases slightly along a transition series. This is because more protons are added in the nucleus, whereas the same number of electrons is added in the (n-1)d subshell, (where n is the number of the period and the quantum number of the s type outer electrons)

Answer 2

Principal quantum number

Because when it increases by 1 (next period) a completely filled orbital is added which causes shielding effect and decreases effective nuclear charge.
