What is the symbol for the following ion electronic structure: 1s^ 2 2s^ 2 2p^ 6 3s^ 2 3p^ 6 3d^ 10 4s^ 2 4p^ 6 4d^ 10 5s^ 2 with an atomic number of 50?

Symbol is Sn

Explanation:

From the periodic table, the element that has an ionic number of 50 and electronic structure of 1s² 2s² 2p^(6) 3s² 3p^(6) 3d^(10) 4s² 4p^(6) 4d^(10) 5s² is known to be Tin.

The symbol for Tin is written as Sn
