===Meaning===
[[Oxygen]] is a [[Group 6]] [[non-metal]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 8.
===About Oxygen===
: [[Oxygen]] makes up 21% of the [[air]].
: [[Oxygen]] has the [[Chemical Symbol|chemical symbol]] [[Oxygen|O]].
====Molecular Structure====
: The [[Chemical Formula|chemical formula]] for a [[Oxygen]] [[molecule]] is [[Oxygen|O<sub>2</sub>]].
====Atomic Structure====
: [[Oxygen]] has 8 [[proton]]s and 8 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number|atomic number]] of 8 and a [[Relative Atomic Mass|atomic mass]] of 16.
: [[Oxygen]] is in [[Period]] 2 of the [[Periodic Table]] because it has 2 [[Electron Orbital|electron shells]].
====Properties====
: [[Oxygen]] is a [[gas]] at [[STP|room temperature]].

====Properties====: [[Oxygen]] is [[gas]] at [[STP|standard temperature and pressure]]. ====Testing for Oxygen====
#Collect the [[gas]] in a [[Test Tube|test tube]].
#Place a glowing [[Wooden Splint|splint]] over the mouth of the [[Test Tube|test tube]].
#If the [[Wooden Splint|splint]] relights then the [[gas]] is [[Oxygen]].
