“Arrange the following atoms in order of increasing effective nuclear charge experience by the electrons in the n=3 electron shell: K Mg P Rh Ti”

Why is this? Are the closer electrons affected more? What about full shells?
Thanks!

Answer #1

The increasing order of effective nuclear charge experienced in the n=3 electron shell is

Mg < P < K < Ti < Rh.

the reason benid this is the Zeffective increases with increase in the atomic number.

Are the closer electrons affected more? What about full shells?

Ans: Yes, the closer electrons have stronger nuclear attraction .

For full shells (completely filled) also the nuclear attraction will be more because atomic size decreases from left to right in the periodic table.
