| 355092 | 2005-05-14 10:02:00 | Greetings people, as the title speaks, I wanted to know why Chlorine is a gas, Bromine is a liquid while Iodine is a solid at room temperature. If possible, could you tell me what keywords should I use in Google or any other search engine? I hope Graham_L or Terry would appear. Cheers :) |

| 355095 | 2005-05-14 10:34:00 | another good example that you could put on that site james, they have real chem teachers there. :) | Prescott (11) | ||
| 355096 | 2005-05-14 11:12:00 | You forgot fluorine, another of the halogen group. Try Googling "halogen". | Richard (739) | ||

| 355099 | 2005-05-14 11:50:00 | Not to mention the extremely exciting and elusive Astatine. James - the simplistic answer is that they are all at different energy levels at any given temperature. Some of these halogens are less energetic than others. Just like Hydrogen and Iron. Of course halogens are very active atoms. They do not exist in nature in a pure form, instead forming salts normally. So when you refer to solids etc, these only exist in laboratories or chemical factories. |

They all have the same energy at the same room temp. It's just that Cl is lighter and so is more volatile. Br is heavier, is a liquid, and I is heavier still, and so is a solid etc. |

It may be related to atomic mass/radius, fluorine is the lightest, then chlorine, then bromine, then iodine , but I'm guessing :) www.chemsoc.org |
