So it does - did I write lead there? That should have been Iron in any case, after Iron forms through fusion it then takes a hell of a lot of energy from the star thus causing its eventual death Sorry about that - don't know what i was thinking about there, will correct it Cheers, Ryan Jones

That must be a pretty late generation star then because elements above lead cannot be formed directly through the thermo-nuclear reactions inside a star, anything after Iron takes in more energy than it emmits and so causies the start to go supernove... The star nust have absorbed that from an interstellar gas cloud and then incorperated into its self but its pretty neat none the less Funny how all the sciences interlink at times like this, its amazing too say the least. Heck, there could be elements made of completly different particles form the ones we know that cna be much larger than ones composed of Protons, Neutrons and Electrons though that is currently a matter for Quantum Physics rather than chemistry but if it is ever found out to be true then chemistry would have a new revolution! "The periodic table could be 3D in shape and extend through a lightyear in each direction" Corrected: Thanks for the correction jdurg Cheers, Ryan Jones

Hi everyone! Brainiac - a mistake in a chemical formula name! Brainiac - I'm shure most of you have heared of it - Science abuse and its quite fun to watch too (Especially the Thermite, oooo Thermite) Anyway, on the Exploding Caravan Golf the person speaking said it was Sodium Carbonate ([ce]Na_2CO_3[/ce]) but was labelled [ce]NaNo_3[/ce] which is clearly Sodium Nitrate! Big mistake there.... Another thing that annoys me are these adverts that go on about all this miricle anti-rinkle formulas and the like. When you lookup the stuff they say most of it is a load of crap and infact most of it is not even found! Amazing the things they put on TV... Cheers, Ryan Jones

Wow, thats impressive - never heared that one before! I wonder is these elements actually occur in larger quantities in stars (Probably have to be 3rd or 4th generation). If a star goes supernova then it is known to form just about ever element currently known (And probably even some more too...) It would be interesting to know if these things can be found in any significant quantities in othe parts of the universe Cheers, Ryan Jones

You can find a lot of threads about it on this forum, searching with the title Phosphorus Insase you do not want too then look here: http://www.scienceforums.net/forums/showthread.php?t=3083 Cheers, Ryan Jones

Seeing as no-one has posted for a few days I'd say the challange has finished which means the winner was cosine who had 119! Congradulations to you all - this is the highest result I have seen on any forum to date Cheers, Ryan Jones

What do you think about that The Thing? I personally think they occur in nature, however small and so are natural. Even if there is a small group of people in a tribe in the Amazon, they may be a tiny group but they are still people, in my oppinion the same applies here Cheers, Ryan Jones

As budullewraagh sad it can happen quite easily. I know Iron wool can burn in a Chlorine atmosphere because I have done so! (Looks great too - lots of sparks )

Yes but even though they are very rare they still are found and therefor are classed as natural Cheers, Ryan Jones

Nope, not as far as I am aware... The bond between Carbon Monoxide and haemoglobin forms a very secure bond, it does not allow the Carbon Monoxide to detatch and thus thats why it is dangerous in large doses Once the caboxyhaemoglobin is formed it must be destroyed as the caboxyhaemoglobin molecule can no longer carry an oxygen.... Cheers, Ryan Jones

There are actually 92 natural and a total of 116. How old if your book and at what study level is it based? The first elements that were found, things like Gols, Filver, Platinum, Copper etc. Were easy to find because they are mostly unreactive and thus exist in their pure (Or almost anyway) forms. Then later as technology and scienctific methods were improved the more reactive eleemtns were found, for example it was found that heating Magnetite with Coal made Iron, then electrolysis was used to extract the thigns like Potassium, Sodium And Cesium. Still later some elements were forums in the universe before they were identified here on Earth, a prome example being Helium (Named Helios after the sun where it was sound in spectroscopy). The as our technology moved still further we could then make our own by smashing smaller atoms together though these only last a fraction of a decond. The group 0 gasses are the one big exception to what I said above, even though they are really, really unreactive due to their stable electron configuration and high ionization energies, they were some of the last to be identified due to the fact they form no compounds (Not strictly true...) and are gasses, makes identifying them very hard Well... thats my summery of the elements, one more thing: thanks to the configuration of the periodic table missing elements properties were "evaluated" even before they ere forund! Incredible If you need anything more specific I'm shure there are loads of people here who could help you with that Cheers, Ryan Jones

Extracting Sulphur can be quite dangerous from what I know' date=' if you heat its orers you could get some [ce']SO_2[/ce] formed and thats not nice stuff. It would probably be cheaper just to buy the stuff and then react it with Carbon Not actually shure if that will work - if not then search Google, I'm shure you'll find what you need Cheers, Ryan Jones

Thart sounds like fun... Do the samething and put it by an ants nest.... LOL... Na, its not funny stuff, not unless you treat it with respect and care anyway Ryan Jones

Sounds like.... Dosen't Carbon Monoxide form a strong bond with Haemoglobin,forming Carboxyhaemoglobin, thus rendering the molecule usless? I would consider that a cumulative effect given enough of it inhaled... Although the blood cells would quiteprobptly be destoyed as a result... Cheers, Ryan Jones

I thgink natural death actually comes down you your genes. Your sels can only coppy themselves xxx number of times before they die, after that they are never replaced. The process is quite slow but as time progresses and you loose more and mlore then it becomes noticable... How about that? Cheers, Ryan Jones

Good idea! Stull, that would take up more than a bit of space don't you think? And somehow your brain can actually link sounds into those images in the correct place! Maybe it stores the images s a set of stil images and then merges them together at the correct rate? Cheers, Ryan Jones

Has anyone ever seen CsOH (Cesium Hydroxide)? I hear that stuff iv nasty with a PH of 15! Cheers, Ryan Jones

Actually I think if the concentration starts rro rise above a certain percent then your liver wil start to break it down, this can have some bad side effects though. Cheers, Ryan Jones

Very true but it still violates the forum policy and I don't fancy getting a warning Cheers, Ryan Jones

Sodium Bromide is normally quite cheap, I have 40g of the stuff here - unused at the time of writing Cheers, Ryan Jones

It does...? Link removed Cheers, Ryan Jones

Thats a bit mean... a great wakeup call though! I read on Google something like this happening though the guy left it in an Aluminium can which dissolved and the stuff went over the floor, dried and went bang when he walked in, it was fun to read! Heres the link: Edit: Removed as it was a link that stated how to make Nitrogen Triiodide... Cheers, Ryan Jones
