**Atomic Number:** 4.

**Protons:** 4

**Electrons:** 4

**Neutrons:**5

**Average Atomic Mass:** 9.0122 g-mol -1

**Discovery:** The element beryllium was discovered not on purpose, but by accident. A chemist called Louis-Nicholas Vauquelin discovered that there was a undiscovered new compound in beryl and emeralds which was the beryllium we all know and love today!(probably not love seeing it is a toxic metal). In 1798 Vauquelin discovered beryllium by taking it from an emerald and lowering the amount of beryllium chloride with potassium in a platinum crucible.


 * Name:** The name for Beryllium comes from the name of the pale gemstone named beryl, a mineral from which beryllium was first taken out of and recognized as different element from aluminum(see discovery).


 * Uses:** Beryllium is the most common window material for X-ray equipment and in particle physics expirements.

 * Interesting Facts**:Beryllium is a rare element because it was created during the Big Bang, and soon after from the act of cosmic rays on interstellar dust. Beryllium is not known to be very useful or necessary for plants or animals.A sample of the element beryllium was hit down with alpha rays from the remaints of radium in a 1932 experiment by James Chadwick that uncovered the existence of the neutron.
