[[Cerium]] is a [[metal]].
==Key Stage 3==
===Meaning===
[[File:CeriumSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Cerium]].]]
[[Cerium]] is a [[Lanthanide]] [[metal]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 58.

===About Cerium===
====Molecular Structure====
: [[Cerium]] has the [[Chemical Symbol|chemical symbol]] [[Cerium|Ce]].
: [[Cerium]] [[atom]]s join together in large numbers to form a giant [[metal]] [[molecule]].
====Atomic Structure====
: [[Cerium]] as 58 [[proton]]s and 82 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 58 and an [[Relative Atomic Mass|atomic mass]] of 140.
: [[Cerium]] is in [[Period]] 6 of the [[Periodic Table]] because it has 6 [[Electron Orbital|electron shells]].
====Properties====
: [[Cerium]] is a [[metal]] [[element]] so it is a good [[Thermal Conductor|thermal conductor]] and a good [[Electrical Conductor|electrical conductor]].
: [[Cerium]] is a shiny [[solid]] at [[STP|room temperature]].
: [[Cerium]] is [[malleable]].
: [[Cerium]] is [[sonorous]].
: [[Cerium]] is [[ductile]].
==Key Stage 4==
===Meaning===
[[Cerium]] is a [[Lanthanide]] [[metal]] [[element]], on the [[Periodic Table]], with 58 [[proton]]s in the [[Atomic Nucleus|nucleus]].
===About Iodine===
====Molecular Structure====
: [[Cerium]] has the [[Chemical Formula|chemical formula]] [[Cerium|Ce]].
