Can someone define an emergent property?

I skimmed through the SEP, but I'm not looking for the whole etymological and ontological history of the term. I just want a solid definition that would be accepted by most philosophers today.

An emergent property is something that happens only once you've assembled enough parts and isn't found in any of the parts. For instance, hydrogen and oxygen aren't thirst quenching on their own, but they become that when mixed in the right ratio.
