In a vast universe, is it possible that a solid gold planet exists?

Edit: What a great discussion! A lot to think about here, especially regarding the implications of infinity.

So it seems that the verdict is that yes, it is in reality POSSIBLE for this to happen, and though it would be incredibly unlikely that a planet consisting of only a single type of ANY element would exist, in a truly infinite universe, this scenario SHOULD occur at least once!

Now for extra credit, does that mean that a solid gold planet would exist an infinite number of times?!?!

Thanks again for all the great comments everyone!

It's really really unlikely. Gold is produced in highly energetic events like supernovae that come with a lot of accompanying matter. 

On a lower energy chemical scale, gold binds to iron really well (which is present in the same events) and makes it highly unlikely to get a planet made purely of gold.
