Answer:
By finding the electron in outermost cell
Explanation:
We will use the condensed form of configuration for Sn2+. Element Sn has 50 electrons, [Kr] includes 36 of those electrons, the other 14 electrons are in: 5s 4d and 5p orbitals. So as you can see, after 2 electrons are removed from the 5p orbital, 5p is no longer part of the configuration.
