Tungsten

Why is the electron configuration for tungsten [Xe]4f^14 5d^4 6s^2 instead of [Xe]4f^14 5d^5 6s^1 because doesn't the d-orbital want to be half filled?

I think it has to do with when filling electrons, the orbitals with the lowest energy/principal quantum number would fill up first so 6s would fill up first, then, 4f, then 5d would fill up last. [Xe]6s^2 4f^14 5d^4
But then you would have to rewrite the electron configuration in order of energy, which according to the value of n so that is why it is written [Xe]4f^14 5d^4 6s^2.
