The ground-state configuration of the elements is the last noble gas of the row above it with the electron configuration. So the elements configuration for a,b, and d would be
silver- [Kr]4d^10 5s
beryllium-[He]2s^2
gallium-[Ar]3d^10 4s^2 4p

Part e for 2.43 asks the electron configuration for Tungsten. How do we do the electron configuration for the f subshell, or do we not need to know this for the midterm?
