aommaster Posted June 14, 2004 Posted June 14, 2004 Would it make a snap or something, or would it be unnoticed?
aommaster Posted June 14, 2004 Posted June 14, 2004 ok. I think because of the small number of atoms that would be involved. I think 17 atoms would be too small for anything
budullewraagh Posted June 15, 2004 Posted June 15, 2004 eh, you never know. Fr is some crazy stuff. if there was more Fr, a reaction between a solution of HF:SbF5 with powdered Fr (to increase surface area) would be insane. Seriously, it would be more powerful than most explosives
aommaster Posted June 16, 2004 Posted June 16, 2004 Just thank God that there are only a few atoms in the world! Could the numbers increase? Because of all the meteors that are falling on earth?
YT2095 Posted June 16, 2004 Posted June 16, 2004 I beleive it`s actualy radioactive too, I know it decays in almost no time flat, hence 17 atoms is an average esstimate, taken at any given time. when you think about it, there`s nothing we could even use to store it in!
YT2095 Posted June 16, 2004 Posted June 16, 2004 Caesium would about the closest element in reactivity to Fr, as stated earlier, that and HF would certainly be a sight to behold (from a safe distance of course).
budullewraagh Posted June 16, 2004 Posted June 16, 2004 of course, of course. and yeah, it's a shame that we can't make a stable isotope of Fr. perhaps that should be my life's work. only problem is that i'd never be able to make a decent amount of Fr; it'd oxidize instantly when in contact with just about anything. yt, do you know how many At atoms have been in existence on earth at any given time? i know it's indredibly rare also, but im just curious as to how it compares with Fr
aommaster Posted June 16, 2004 Posted June 16, 2004 Hmm... what about making a lump of it, it would be then like aluminium, with an oxidised covering at the top, but, completely pure in the middle!
YT2095 Posted June 16, 2004 Posted June 16, 2004 yt, do you know how many At atoms have been in existence on earth at any given time? i know it's indredibly rare also, but im just curious as to how it compares with Fr no I don`t, sorry I do know also that it is rare and radioctive though, I did a search a few years ago for Lithium Astatide, wondering what the probability of it`s existance would be, being as they seem to be the least reactive if you don`t count Hydrogen, there were no results at that time maybe you could do a search now and get a result, I don`t know? but when I looked there was nowt LOL
wolfson Posted June 16, 2004 Posted June 16, 2004 One isotope of Francium (223Fr) has a half life of 21.80 minutes, made by alpha decay, and is normally studied in laser atom traps. Astatine can be produced by bombarding bismuth with energetic alpha particles to obtain the relatively long-lived 209-211At, which can be distilled from the target by heating in air.
aommaster Posted June 16, 2004 Posted June 16, 2004 Good info, but I think we seem to have drifted away from the actual topic
aommaster Posted June 16, 2004 Posted June 16, 2004 See? This was the problem, and somehow I got involved with a conversation about acids and alkalis This problem seems really easy (and probably is) but I am troubled by it for some reason. I can't remember it exactly because it was on a test in my high school chem. class today. What is the pH of a solution that has 12.00 g Na(OH)2 and 250.0 mL H2O?
budullewraagh Posted June 16, 2004 Posted June 16, 2004 Na(OH)2 that isn't right...you must be speaking of NaOH Na(OH)2 wouldn't exist...
YT2095 Posted June 16, 2004 Posted June 16, 2004 to put the poor guy out of his missery, look for a calc that`ll give you a Ph of about 4.5 to 4.44 (avg 4.47(ish)). that`s an "off the top of my head" figure from memory, but do NOT take my word for it! I COULD be wrong!
aommaster Posted June 16, 2004 Posted June 16, 2004 I COULD be wrong! I think that would be highly unlikely
YT2095 Posted June 16, 2004 Posted June 16, 2004 well I am working from memory that was about 20 year ago with a similar (if not the same question) and I rem 4.44 as being significant, same as when I had an Avogadro party when I was 23 and we played a Molarity game WITHOUT CALCULATORS! as well as Guess the Element and Beer for Reaction Loser, sad I know but I was only a kid then and it was fun I`ll go with 4.47 on this one tho`, and yes I really COULD be wrong! ) it`s nice when folks have faith in you, but faith and Science don`t always make good !
YT2095 Posted June 16, 2004 Posted June 16, 2004 actualy, Ignore my last few posts 4.44 to 4.5 was the stability buffer for an indicator. typing that post`s helped me remember, it was about buffer agents! sorry all!
budullewraagh Posted June 16, 2004 Posted June 16, 2004 that is incredible. i wish i had friends who were that enthused by chem
YT2095 Posted June 16, 2004 Posted June 16, 2004 ) 14.08 should be his answer though (I think) LOL 12g in 250ml should be about that
QuarkQuarkQuark2001 Posted June 17, 2004 Posted June 17, 2004 which element is the most reactive? And does there any element that francium mix with would give a more reactive rate than with fluorine?
