Valence Electrons in d orbital
How do you determine the number of valence electrons in the d block? Does it have to be either one or two since?

Re: Valence Electrons in d orbital
Valence electrons refer to the outermost electrons in the outermost shells, so usually when an atom has a d orbital, you would just count the electrons in the s and p shells. If you are referring to how many electrons can be in each orbital of the d shell, then yes there can be one or two electrons in each orbital.

Re: Valence Electrons in d orbital
The number of valence electrons in the d orbital is determined by the element. However, it's important to remember that the 3d orbital has a lower energy level than the 4s orbital, and therefore is filled first. For example, Ni would have an electron configuration of [Ar]3d^10 rather than [Ar]3d^8 4s^2.
