Once in chemistry lesson at school we had to go to the teacher's desk to watch some chemical experiment. There was a box with chemical compounds on the desk, also a brown bottle which seemed to be empty. It seemed like a good idea back then to open and smell it. It felt like even the farthest corners of my nasal cavity and my sinuses were filled with horrible stench that i can't describe.I felt sick and the smell in my nose stayed for several days. There was a tiny amount of Bromine in the flask

Ah, Bromine, along with Mercury, they are the only elements that are liquid in room temperature. Also, both are very toxic. Halogen group is interesting because it has elements in all three forms, fluorine and chlorine are gases, bromine is liquid and iodine is solid in room temperature. This is because iodine has most electrons from these, so the attraction force between molecules is greater, requiring more energy to break these bonds.

2:43 The experimentator mixes up bromine and aluminium as oxidizing. First he says it right: "The bromine is a strong oxidizer", then he mixes it up as he says "as I said the aluminium is strongly oxidizing". In fact aluminium is the reducing agent being oxidized by bromine (Al -> Al+ + 1e- and Br2 + 2e- -> 2 Br-). Oxidation here is meant as giving electrons, Reduction is receiving electrons. Since Al gives electrons it is itself oxidized and reduces the bromine, thus being the reducing agent (to bromine) not the oxidizer. Bromine is reduced and is itself oxidizing the aluminium. It is complicated, so don't get desperate.
@GravelLeft10 жыл бұрын
I think what he meant to say is that aluminium has an oxide layer and that is why it takes some time for the reaction to start. I'm pretty shure that's what he meant because he said: "... it generally takes a few moments for this reaction to start, because as I said, the aluminium is strongly oxidising..", and that sentence doesn't really make much sence, does it? It makes more sence if what he meant to say was "it takes some time for this reaction to start because aluminium has an oxide layer".

Wouldn't it be aluminum bromide instead of aluminum tribromide? Prefixes are only used when there is a nonmetal reacting with a nonmetal. Also, because aluminum only has one oxidation state, there is no need to put any Roman numerals.

Actually, I'm not sure. There are weird things going on with these heavy elements due to the effects of special relativity. In somewhat oversimplified terms, the outer electrons of heavy elements are moving so fast that they actually become heavier, and therefore they sink towards the nucleus somewhat. The reactivity of alkali metals depends on having a very loosely bound outer electron, so this relativistic effect means francium is actually less reactive than caesium - at least according to scientific calculations, though this would be difficult to ever test experimentally. If the trend of increasing reactivity for alkali metals reverses when you get to francium, perhaps the same is true for the trend of decreasing melting points. Those calculations are harder to do, since for melting/boiling you have to look simulate lots of atoms, whereas for reactivity you only need to simulate one. I don't know whether anyone has done the maths. What is true, though, is that you ever managed to get a bulk sample of francium together it wouldn't stay solid for long - not because of its melting/boiling point so much as the enormous amount of heat produced by its own radioactivity would cause it to vaporise.
@swabianscience6 жыл бұрын
Actually, the math has been done and according to the English Wikipedia, it's solid with a melting point at about 30°C. But it seems those calculations aren't very accurate, I noticed the German Wikipedia sees Copernicium as a liquid element at standard temperature, while the English Wikipedia predicts it to be gaseous... Probably nobody can say it for sure, and, to be honest, I don't think it will ever matter

Actually, the better question would be, why do American's call it "aluminum"? Most of the rest of the world spells it "-ium" like most other metallic elements and pronounces it accordingly. "-ium" is the spelling adopted by the International Union of Pure and Applied Chemistry (IUPAC). It was originally called "alumium", then "aluminum" but "aluminium" rapidly became most common. Americans probably use "aluminum" because, for a long time, the major US manufacturer preferred that spelling.
