Question

What type of element has the electron configuration `[Kr]5s^2 4d^10 5p^2`?

Answer 1

A tinny element...

Explanation:

If the element has got such a configuration it has `36+2+10+2=50*"electrons"`...then the neutral element MUST have 50 protons, i.e. `Z_"the atomic number"=50`.... If only there were something that listed the names of the elements according to their atomic number....
