The facts of Beryllium products
Beryllium is a chemical element with symbol Be and atomic number 4. It is created through stellar nucleosynthesis and is a relatively rare element in the universe. It is a divalent element which occurs naturally only in combination with other elements in minerals.
Uniquely strong and light, beryllium is used to make cell phones, missiles and aircrafts. But workers who handle the metal need to watch out, as airborne beryllium has been known to be highly toxic.
