Question: Does the density of different atoms affect their properties?If so how?

Sean Murphy answered on 16 Mar 2012:

Yes, the best way to describe this is to consider atoms of oxygen (O2). If oxygen atoms were very very dense, they would interact in a way to become a solid. If they became slightly less dense, then they would form a liquid. Even less dense still and they would become a gas. The density of atoms can be affected by changing either the temperature or pressure.
