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 $5 {p}^{2}$
The total electron configuration would be
$1 {s}^{2} 2 {s}^{2} 2 {P}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 3 {d}^{10} 4 {p}^{6} 5 {s}^{2} 4 {d}^{10} 5 {p}^{2}$

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

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
$\left[K r\right] 5 {s}^{2} 4 {d}^{10} 5 {p}^{2}$

I hope this was helpful.
