Hmm...today Mdm Riza showed us a video of what happen when certain metals were dropped into water.you might think that metals just sink and rust in water...but thats only for iron and metals like it...there is a wide variety of metals so why not thinking of other metals?
so yea..the video started off with a metal moving around in a large bowl of water and giving off nitrogen in the form of a white gas.that was the reaction of the metal.then another metal was dropped.that metal has a higher atomic number.so since it has more atoms in it,the metal give off nitrogen at a faster rate.
then the third metal was dropped.the atomic number of the metal increases as the number of metal dropped increases.so this time the release of nitrogen was so fast that the nitrogen caught fire.then the following metals exploded upon contact with the water...the last few were so large that the camera crew had to put protective glass in front of them...so yea..
