==Key Stage 2==
===Meaning===
[[Iodine]] is a purple [[solid]].
==Key Stage 3==
===Meaning===
[[File:IodineSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Iodine]].]]
[[Iodine]] is a [[Group 7]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 53.
===About Iodine===
====Molecular Structure====
: [[Iodine]] has the [[Chemical Formula|chemical formula]] [[Iodine|I<sub>2</sub>]].
====Atomic Structure====
: [[Iodine]] as 53 [[proton]]s and 74 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 53 and an [[Relative Atomic Mass|atomic mass]] of 127.
: An [[atom]] of [[Iodine]] is missing one [[electron]] from having a full [[Outer Shell|outer shell]].
: [[Iodine]] [[ion]]s gain 1 [[electron]] to get a full [[Outer Shell|outer shell]] and become [[Negative Charged|negatively charged]].
====Properties====
: [[Iodine]] is a [[non-metal]] [[element]].
: [[Iodine]] is a more [[Reactivity|reactive]] [[Halogen]] than [[Astatine]] but less [[Reactivity|reactive]] than [[Bromine]].
: [[Iodine]] [[Chemical Reaction|reacts]] with [[Hydrogen]] to produce [[Hydrogen Iodide]] which [[dissolve]]s in [[water]] to produce [[Hydroiodic Acid]].
: [[Iodine]] is a mild [[bleach]]ing agent.
: [[Iodine]] kills [[bacteria]].
: [[Iodine]] is a purple [[solid]] at [[STP|room temperature]].
==Key Stage 4==
===Meaning===
[[Iodine]] is a [[Group 7]] [[element]], on the [[Periodic Table]], with 53 [[proton]]s in the [[Atomic Nucleus|nucleus]].
===About Iodine===
====Molecular Structure====
: [[Iodine]] has the [[Chemical Formula|chemical formula]] [[Iodine|I<sub>2</sub>]].
: [[Chlorine]] [[atom]]s join together in a [[Covalent Bond|covalent bond]].
