[[File:ErbiumSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Erbium]].]]
[[Erbium]] is a [[Lanthanide]] [[metal]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 68.
===About Erbium===
====Molecular Structure====
: [[Erbium]] has the [[Chemical Symbol|chemical symbol]] [[Erbium|Er]].
: [[Erbium]] [[atom]]s join together in large numbers to form a giant [[metal]] [[molecule]].
====Atomic Structure====
: [[Erbium]] as 68 [[proton]]s and 99 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 68 and an [[Relative Atomic Mass|atomic mass]] of 167.
: [[Erbium]] is in [[Period]] 6 of the [[Periodic Table]] because it has 6 [[Electron Orbital|electron shells]].
====Properties====
: [[Erbium]] is a [[metal]] [[element]] so it is a good [[Thermal Conductor|thermal conductor]] and a good [[Electrical Conductor|electrical conductor]].
: [[Erbium]] is a shiny [[solid]] at [[STP|room temperature]].
: [[Erbium]] is [[malleable]].
: [[Erbium]] is [[sonorous]].
: [[Erbium]] is [[ductile]].
==Key Stage 4==
===Meaning===
[[Erbium]] is a [[Lanthanide]] [[metal]] [[element]], on the [[Periodic Table]], with 68 [[proton]]s in the [[Atomic Nucleus|nucleus]].
===About Iodine===
====Molecular Structure====
: [[Erbium]] has the [[Chemical Formula|chemical formula]] [[Erbium|Er]].
: [[Erbium]] [[atom]]s join together in a [[Giant Metallic Structure|giant metallic structure]].
====Atomic Structure====
: The most [[Stable Isotope|stable isotope]] of [[Erbium]] has 99 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Relative Atomic Mass|atomic mass]] of 167.
: [[Erbium]] is in [[Period]] 6 of the [[Periodic Table]] because it has 6 [[Electron Orbital|electron shells]].
: [[Erbium]] loses [[electron]]s to form [[Positive Charge|positive]] [[Metal Ion|metal ions]].
====Properties====
: [[Erbium]] forms [[Ionic Bond|ionic bonds]] with [[non-metal]]s.
: [[Erbium]] is a [[metal]] [[element]] so it is a good [[Thermal Conductor|thermal conductor]] and a good [[Electrical Conductor|electrical conductor]].
: [[Erbium]] is a shiny [[solid]] at [[STP|standard temperature and pressure]] and has a high [[Melting Point|melting point]].
: [[Erbium]] is [[malleable]].
: [[Erbium]] is [[sonorous]].
: [[Erbium]] is [[ductile]].
