Are we expected to know the number of valence electrons in transition metals? It was a homework problem, so I wanted to make sure. The problem stated to identify the number of valence electrons (including d electrons) in magnesium. If we are expected to know this, how would we determine the number?

You can usually identify the number of valence electrons by looking at the periodic table, which will be given on exams. All you have to do is count the groups leading up to the atom. In other words, know how many electrons are in the outer shell of the electron configuration of the atom.
