naturally occuring metals in pure form are considered transition elements?

[Smooth Operater]

According to one of kaplan's subject exam questions, naturally occuring metals in pure form are considered transition elements. Why? I though metals found in group IA and IIA are naturallay occuring metals.

I think the key here is "in pure form." Usually metals in IA, IIA such as Na, K are present as salts/ions. In their pure forms, the are extremely reactive and thus unlikely to be found in nature. Correct me if I am wrong though!

You're right, first two groups are too reactive and not found in their pure form.
