My last chemistry class was in the 7th grade (currently 10th grader) so bear with me. Last year duing a biology class we were talking about ecology and how phosphorus would cycle through the environment. The reason that the phosphorus cycle is interesting is because phosphorus cannot be a gas, or so my teacher said. I Immediatly questioned this because in my chemistry class i remeber hearing that elements can be in any of the 4 states, but my teacher insisted that it could not. So, who was right?
