===Meaning===
===About Lithium===
====Molecular Structure====: [[Lithium]] has the [[Chemical FormulaSymbol|chemical formulasymbol]] [[Lithium|Li]].: [[Lithium]] [[atom]]s join together in large numbers to form a giant [[metal]] [[molecule]].====Atomic Structure====
: [[Lithium]] has 3 [[proton]]s and 4 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 3 and an [[Relative Atomic Mass|atomic mass]] of 7.
: An [[atom]] of [[Lithium]] has only 1 [[electron]] in its [[Outer Shell|outer shell]].
====Properties====
: [[Lithium]] is the least [[Reactivity|reactive]] [[Alkali Metal]].
: [[Lithium]] is more [[Reactivity|reactive]] than [[Carbon]] on the [[Reactivity Series|reactivity series]] so it must be [[Extraction of Metals|extracted]] from its [[ore]] using [[electrolysis]].
: [[Lithium]] [[Chemical Reaction|reacts]] strongly with [[water]] to produce [[Hydrogen]] [[gas]] and [[Lithium Hydroxide]].
: [[Lithium]] is a [[solid]] at [[STP|room temperature]].
==Key Stage 4==

[[File:Li-7_WK.PNG|right|200px|thumb|A 2 dimensional representation of the [[Bohr Model]] of a [[Lithium]]-7 [[isotope]] with 3 [[proton]]s and 4 [[neutron]]s in the [[Atomic Nucleus|nucleus]] and 2 [[electron]]s in the first [[Electron Orbital|shell]] and 1 in the [[Outer Shell|outer shell]].]]
===Meaning===
[[Lithium]] is a [[Group 1]] [[element]] , on the [[Periodic Table]], with 3 [[proton]]s in the [[Atomic Nucleus|nucleus]].
===About Lithium===
====Molecular Structure====: [[Lithium]] has the [[Chemical FormulaSymbol|chemical formulasymbol]] [[Lithium|Li]].: [[Lithium]] [[atom]]s join together in a [[Giant Metallic Structure|giant metallic structure]].====Atomic Structure====
: The most [[Stable Isotope|stable isotope]] of [[Lithium]] has 4 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Relative Atomic Mass|atomic mass]] of 7.
: An [[atom]] of [[Lithium]] has only 1 [[electron]] in its [[Outer Shell|outer shell]].
: [[Lithium]] [[ion]]s have lost an [[electron]] to become [[Positive Charge|positively charged]].

====Properties====
: [[Lithium]] is the least [[Reactivity|reactive]] [[Alkali Metal]].
: [[Lithium]] is more [[Reactivity|reactive]] than [[Carbon]] on the [[Reactivity Series|reactivity series]] so it must be [[Extraction of Metals|extracted]] from its [[ore]] using [[electrolysis]].
: [[Lithium]] [[Oxidation|oxidises]] quickly in the presence of [[Oxygen]] so it must be stored in [[oil]].
: [[Lithium]] [[Chemical Reaction|reacts]] strongly with [[water]] to produce [[Hydrogen]] [[gas]] and [[Lithium Hydroxide]].
: [[Lithium]] is a [[solid]] at [[STP|standard temperature and pressure]] with a [[Melting Point|melting point]] of 180.50 [[Degrees Celsius|°C]].
