What is the abbreviated electron configuration of Sn?

Tin - Sn, on is found in the fourteenth column of the periodic table Group IVB this is the second column of the p block. Tin is in the fifth energy level (row).

This means that Tin must end with an of ##5p^2## The total electron configuration would be ##1s^2 2s^2 2P^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^2##

The noble gas Krypton has an electron configuration of ##1s^2 2s^2 2P^6 3s^2 3p^6 4s^2 3d^10 4p^6##

So we can replace this portion of tin's electron configuration with the noble gas notation [Kr]

This makes the electron configuration for Tin - Sn ##[Kr] 5s^2 4d^10 5p^2##

I hope this was helpful. SMARTERTEACHER
