Well, you should really get to know your periodic table...

Look up magnesium, argon, copper, and silicon. Where do you see #"Mg"#? #"Ar"#? #"Cu"#? #"Si"#? The transition elements are in the pink region, atomic numbers #21 - 29#, #39 - 47#, #57 - 79#, and #89 - 111#.

Or, if you want a filtered version...

Which of these elements lies in that range of atomic numbers?
