What is a transition metal?

So where does magnesium fit into this classification? Magnesium is located in group 2 of the periodic table, also known as the alkaline earth metals. Like the other alkaline earth metals, it has a filled s orbital and two valence electrons. Unlike the transition metals, it does not have any partially filled d orbitals in its atomic structure. Therefore, magnesium is not classified as a transition metal.
