[[File:BerylliumSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Beryllium]].]]
[[Beryllium]] is a [[Group 2]] [[element]] , on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 4.
===About Beryllium===
: [[Beryllium]] has the [[Chemical Formula|chemical formula]] [[Beryllium|Be]].
: [[Beryllium]] as 4 [[proton]]s and 5 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 4 and an [[Relative Atomic Mass|atomic mass]] of 9.
: [[Beryllium]] is the least [[Reactivity|reactive]] [[Alkali Earth Metal|alkali earth metal]].
: [[Beryllium]] is more [[Reactivity|reactive]] than [[Carbon]] on the [[Reactivity Series|reactivity series]] so it must be [[Extraction of Metals|extracted]] from its [[ore]] using [[electrolysis]].
: [[Beryllium]] [[Chemical Reaction|reacts]] strongly with [[steam]] to produce [[Hydrogen]] [[gas]] and [[Beryllium Hydroxide]].
: An [[atom]] of [[Beryllium]] has only 2 [[electron]]s in its [[Outer Shell|outer shell]].
: [[Beryllium]] [[ion]]s have lost 2 [[electron]]s to become [[Positive Charged|positively charged]].
