You can calculate the number of valence electrons of transition metals by counting the number of electrons outside the ultimate noble gas core.

e.g (1) Chromium: #[Ar]3d^(5)4s^(1)#

This means there are 6 valence electrons available for bonding.

e.g (2) Zirconium: #[Kr]4d^(2)5s^(2)#

This means there are 4 valence electrons available for bonding.
