Transition Metal Valence Electrons

[Natalie_Martinez_1I]

I'm confused like on the number of valence electrons of transition metals. For example why does Ti have 4 valence electrons if it only has 2 electrons in the s orbital and none in the p?

I believe you look at the 2 electrons in the 4s2 and the two electrons in the 3d2. This would be a total of 4 electrons ie. your four valenece electrons.

It usually helps to draw out the electron configuration diagram. For example, for Ti, its electron configuration is [Ar]4s^2 3d^2 so it would make sense for it to have 4 valence electrons from the outermost 4s electrons and the 3d electrons.

By this same logic, how many valence electrons would copper? can someone explain please
