22) Write ground state electron conigurations for the following elements. (4) Copper Iodine Rubidium Tin Write the condensed electron configurations of the following elements.(4) chromium chlorine silver tellurium Write the ground state electron configurations for the following ions. (4) 02. Fe P3- 2+ Cd

Solution

Ans 22 :

The electronic configuration of elements depend on the number of electrons present in the atom.

So here :

Copper : 1s2 2s2 2p6 3s2 3p6 3d10 4s1

Iodine : 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p5

Rubidium : 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s1

Tin : 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p2

chromium : [Ar] 3d5 4s1

Chlorine : [Ne] 3s2 3p5

silver : [Kr] 4d10 5s1

tellurium : [Kr] 4d10 5s2 5p4

O^2- : 1s2 2s2 2p6

Fe³⁺ : 1s2 2s2 2p6 3s2 3p6 3d5

P^3- : 1s2 2s2 2p6 3s2 3p6

Cd²⁺ : 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10
