Strontium and lithium dissolves in water forming the corresponding hydroxide and liberating hydrogen. However the reaction is exothermic and may cause explosion / fire.
Lithium, sodium, and potassium react vigorously with water to form hydroxides and release hydrogen gas. The reactivity increases as you go down the group from lithium to potassium, with potassium being the most reactive.
penicillin and lithium be takin together
Technicaly, its lighter than oxigen, nitrogen, and all the other gasses, (i believe) exept hydrogen and helium. so yes, i SOULD be lighter than air, but if you let go of it, it will fall. but it is the lightest metal. So in conclusion, i should be lighter than air, but.isn't. how interesting!
They sink.
it get rusted
You need to go further away to find water.
Generally no. But it is corrosive, reactive and it cannot be extinguished with water if it burns. Lithium reacts with water to form a strong alkali which attacks skin. (It is the water in air that exposed metal reacts with.) Lithium is stored as a "bulk metal" in a petrolium liquid such as kerosene or naphtha. And those fluids are combustable. It is critically important to have your head on straight when working around this stuff, and even more so when handling it. Use the link to the Wikipedia article on lithium and check out the precautions.
You will need to go to the loo
short circuit
You will need to go to the loo
You would blow up from water pressure.
it explodes man
