The only two metals from the Periodic Table that are colored are Gold (Au) and Copper(Cu)
Gold and Copper Are the only colored metals other than different shades of gray and black and whatnot
The transition metals tend to form colored compounds.
Colored ions are normally associated with the transition metals, which aren't actually a "group" in the usual chemical sense of the word. Also, they don't have to be in aqueous solutions.
The chemistry is about d electrons. They are all metals. The vast majority of their compounds are colored.
Non metals cannot emit a colored light.
Yes. Different metals, different color.
iron, nickel, cobalt & Steel
Transition Metals
Most transition metals form colored ion-complexes.
Mg
Mg
An alloy like steel, a homogenous mixture of metals (and some nonmetals as well).
