Ok fair Enough. although it wasnt 100% pure Fr it was synthesised by the combining of other elements with a total of 68%pure Fr although we must do more research as it was producing a few rads?
May i sudjest you do a video on electrolosis of NaCI to form pure Na always a good hit. but dont use Na0h as it eats through aluminium and glass when molten
I won't be doing a video on the electrolysis of NaCl, since I don't have the apparatus and the hazards are high enough that it's something I don't really want to put into the public domain. Anyway, interesting though it is, it's not that dramatic for an audience.
@hermanntrude There is a video of electrolysis of CaCl2 and another one with NaOH. Electrolysis of NaCl is not dangerous as long as there is ventilation. As for molten NaOH, it is extremely dangerous so being fully covered and face shield are important.
Vanadium i do not know why i said that i meant Rb and i beg to differ your theory of no one seeing fr we have used .01g 0.1 0.3 grams of it at my lab at the Sydney Csiro although i am not to tell you the reasons acourding to my boss so best of luck. we made Na at uni using two copper electrodes and molten sodium always fun but do not use Na0h it eats through glass at molten temp
now rubidium I can agree with you on. Although there is still a slight difference in that you can be absolutely sure rubidium will explode, whereas you're never certain with potassium and particularly sodium, which are quite unpredictable.
My comment was made on the basis that many people can easily obtain a lot of sodium for free whereas rubidium is more tightly controlled.I am intrigued by your statement about francium. I had heard that there were less than 2gof francium in the entire crust.
You Say potassium and sodium metals are the most dangerous alkali metals eh? have you never heard of or used vanadium caesium or francium? i think you should do some study on them
I'm not too sure about vanadium, but it certainly doesn't explode on contact with water. As for caesium, it's surprisingly lame when reacting with water, mostly because a gram of caesium contains substantially less atoms than a gram of sodium.. As for Francium, it's radioactive and extremely rare. So rare, in fact that no one has ever seen a visible quantity of francium metal.
awesome...i certinally hope that that DVD is a copy of Mariah Carey's Glitter...or even better any movie with J.Lo...haha Br for cuts?? he must have gotten confused with Iodine...i know ppl thought u should put Hydrogen Peroxide on...but they found it kills more than it should...so good old water and soap...Hi Vince!!...haha
Great Job Herman!.....liked the way you didn't correct the student when suggesting N to speed it up....researched and corrected yourself on the Bromine in a cut idea (yikes!), and added very thorough notes on clean-up, safety issues, interesting points of the subjects, etc. Your enthusiasm, thoroughness, avoidance of chastisement for incorrect answers, modesty and humbleness will serve you and your students well.

blank DVD. I considered a whole bunch of politically motivated DVD choices, but eventually I decided I was above political hatemongering.
