How to calculate valency of d block from we electronic configuration

Expert Answer:

The number of valence electrons in d-block elements is most often equal to their group number which is equal to the number of electrons in the "valence shell."
for example, scandium metal's electrons per shell are 2,8,9,2 and its outer shell has only 2 electrons, so the valence electron count of scandium is 2.
