### Electron Configuration for Tungsten (W)

Posted: Tue Oct 13, 2015 8:34 pm
Why is the electron configuration for tungsten $4f^{14}5d^{4}6s^{2}$ instead of $4f^{14}5d^{5}6s^{1}$? Shouldn't the 6s orbital lend an electron to the 5d orbital for a more stable half-orbital?
This is based on the answer for 2.43 from the textbook, part e).
