Are atoms on earth the same across the universe?

Question

Do the dynamics of atoms and their properties hold true across the universe?

In: Chemistry

Answer 1

Mostly yes. But there are some atoms in the universe at temperatures that do not naturally occur on Earth. So those are going to behave differently (but if you somehow took an atom from Hearth to those temperatures, it would be the same).

Then you also have difference in just how common some atom is. For example, Helium is one of the most common atoms in the universe, but it’s comparatively pretty rare on Earth.
