Lithium (new) - Periodic Table of Videos

lithium is the lightest metal we all know that sodium is pretty light as a metal if you drop it onto water and forget the reaction it floats to the

orange sodium blame it on your camera of course let him will do the same that their differences which are so you in a

minute but I wanted to see was whether we could demonstrate how much lighter lithium was than sodium would never try this experiment but fall but I asked

Neil technician to drop piece of sodium and the piece of lithium of approximately the same size at the same time in two beakers of hexane hexane is

similar to gasoline or petrol and when he dropped them it was really striking the sodium sank like a stone because gasoline is much less dense than water

but lithium bumped around like a little boat if you look carefully they both started bubbling because we didn't use try a hexane and both samples of hexane

contained just a little bit of water that started reacting and of course that prompted need to want to drop the lamps of metal into real water so we tried

experiments again dropping litter him and sodium into water goes this time both of them loaded but lithium is less reactive towards water

and sodium it's a small erratum the electrons are more tightly health and the reaction is slower with the sodium it was really quite surprising it went

off with a real bang ended up in the back of the fume cupboards the sodium was gone and the lithium quietly buzzed around on the surface of
