If this is a 2+ ion, then the electron configuration for element must be [Kr]4d10 5s2 5p2
Determine what element you're dealing with. Kr has 36e, and you have 14 more which makes 50e total. Element 50 is what? So you write that element symbol down (I'll call it X) and add the charge like X^2+ (or X^++) and you have it.
