Nearest noble gas to this element is Krypton which has an atomic number 36.
Electronic configuration or noble-gas notation for Sn is written as :
![Sn=[Kr]4d^{10}5s^25p^2](https://tex.z-dn.net/?f=Sn%3D%5BKr%5D4d%5E%7B10%7D5s%5E25p%5E2)
As seen from above, Noble gas Krypton having symbol 'Kr' is coming in the electronic configuration for Tin.
