Arrange the following atoms in order of increasing effective nuclear charge experienced by the electrons in the n=3 electron shell: K, Mg, P, Rh, and Ti. Explain the basis for your order.

Verified Answer :

I think that the effective nuclear charge increases as you go up a group and across a period. 

so maybe Rh, K, Ti, Mg, P 

 I hope I helped :)

The arrangement of the atoms in order of increasing effective nuclear charge experienced by the electrons in the n=3 electron shell is; Rh < Ti < K < Mg < P.

The effective nuclear charge experienced by electrons in an atom is a function of the distance of the electrons from the nucleus of the atom.

  • In essence, the effective nuclear charge on electrons increases across a period and decreases down a group.

  • Therefore, the effective nuclear charge in the n=3 electron shell in increasing order is;

Rh < Ti < K < Mg < P.

This is so because;

  • Rh -- Period 5, group 9

  • Ti -- Period 4, group 4

  • K --Period 3, group 1

  • Mg --Period 2, group 2

  • P --Period 2, group 5.
