[[File:ArsenicSymbol.png|right|300px|thumb|The [[Chemical Symbol|chemical symbol]] for [[Arsenic]].]]
[[Arsenic]] is a [[Group 5]] [[metalloid]] [[element]], on the [[Periodic Table]], with an [[Atomic Number|atomic number]] of 33.
===About Arsenic===
: [[Arsenic]] has the [[Chemical Symbol|chemical symbol]] [[Arsenic|As]].
====Atomic Structure====
: [[Arsenic]] as 33 [[proton]]s and 42 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Atomic Number]] of 33 and an [[Relative Atomic Mass|atomic mass]] of 75.
: [[Arsenic]] is in [[Period]] 4 of the [[Periodic Table]] because it has 4 [[Electron Orbital|electron shells]].
====Properties====
: [[Arsenic]] is a shiny [[solid]] at [[STP|room temperature]].
==Key Stage 4==

===About Iodine===
: [[Arsenic]] has the [[Chemical Symbol|chemical symbol]] [[Arsenic|As]].
====Atomic Structure====
: The most [[Stable Isotope|stable isotope]] of [[Arsenic]] has 42 [[neutron]]s in its [[Atomic Nucleus|nucleus]] giving it an [[Relative Atomic Mass|atomic mass]] of 75.
: [[Arsenic]] is in [[Period]] 4 of the [[Periodic Table]] because it has 4 [[Electron Orbital|electron shells]].
: [[Arsenic]] loses [[electron]]s to form [[Positive Charge|positive]] [[Metal Ion|metal ions]].
====Properties====
: [[Arsenic]] is a [[metalloid]] [[element]] so in some conditions it is an [[Electrical Conductor|electrical conductor]].
: [[Arsenic]] is a shiny [[solid]] at [[STP|standard temperature and pressure]] and has a high [[Melting Point|melting point]].
