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. You can see the orange sodium flame. Oh, It's on the camera. Of course, lithium will do the same, though, there are differences which I will show you in a minute. But what I wanted to see was whether we could demonstrate how much lighter lithium was than sodium. We've never tried this experiment before, but I asked Neil, our technician, to drop a piece of sodium and a piece of lithium of approximately the same size, at the same time into 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 le...
