What are its uses?
 Did You Know? Because beryllium is one of the lightest metals and has one of the highest melting points of light metals, it has been used in structures for high speed aircraft and missiles. Because it also does not spark, it is used in non-sparking tools. Because it reacts with the alpha particles released by polonium to produce neutrons, it is used in A-bomb initiators. And finally, because it does not react with acid and uranium it is used to make nuclear generators.
