[[File:ThoriumSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Thorium]].]]
[[Thorium]] is a [[Actinide]] [[metal]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 90.
===About Thorium===
====Molecular Structure====
: [[Thorium]] has the [[Chemical Symbol|chemical symbol]] [[Thorium|Th]].
: [[Thorium]] [[atom]]s join together in large numbers to form a giant [[metal]] [[molecule]].
====Atomic Structure====
: [[Thorium]] as 90 [[proton]]s and 142 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 90 and an [[Relative Atomic Mass|atomic mass]] of 232.
: [[Thorium]] is in [[Period]] 7 of the [[Periodic Table]] because it has 7 [[Electron Orbital|electron shells]].
====Properties====
: [[Thorium]] is a [[metal]] [[element]] so it is a good [[Thermal Conductor|thermal conductor]] and a good [[Electrical Conductor|electrical conductor]].
: [[Thorium]] is a shiny [[solid]] at [[STP|room temperature]].
: [[Thorium]] is [[malleable]].
: [[Thorium]] is [[sonorous]].
: [[Thorium]] is [[ductile]].
==Key Stage 4==
===Meaning===
[[Thorium]] is a [[Actinide]] [[metal]] [[element]], on the [[Periodic Table]], with 90 [[proton]]s in the [[Atomic Nucleus|nucleus]].
===About Iodine===
====Molecular Structure====
: [[Thorium]] has the [[Chemical Formula|chemical formula]] [[Thorium|Th]].
: [[Thorium]] [[atom]]s join together in a [[Giant Metallic Structure|giant metallic structure]].
====Atomic Structure====
: The most [[Stable Isotope|stable isotope]] of [[Thorium]] has 142 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Relative Atomic Mass|atomic mass]] of 232.
: [[Thorium]] is in [[Period]] 7 of the [[Periodic Table]] because it has 7 [[Electron Orbital|electron shells]].
: [[Thorium]] loses [[electron]]s to form [[Positive Charge|positive]] [[Metal Ion|metal ions]].
====Properties====
: [[Thorium]] forms [[Ionic Bond|ionic bonds]] with [[non-metal]]s.
: [[Thorium]] is a [[metal]] [[element]] so it is a good [[Thermal Conductor|thermal conductor]] and a good [[Electrical Conductor|electrical conductor]].
: [[Thorium]] is a shiny [[solid]] at [[STP|standard temperature and pressure]] and has a high [[Melting Point|melting point]].
: [[Thorium]] is [[malleable]].
: [[Thorium]] is [[sonorous]].
: [[Thorium]] is [[ductile]].
