For my homework I have been asked to say which elements in the reactivity series are found in their natural form and which aren't. I also have to say what natural form means. I have looked on the internet and Wikipedia is closed today so I can't go on it.

I think they refer to the fact that, for example, gold which isn't very reactive is found as the element, but sodium which is very reactive is always found as compounds.

Thanks for the answer

Platinum is even less reactive than Gold.
