Tin - Sn, on the periodic table 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 electron configuration 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.
