'''Fluorine''' is the lightest member of the [[halogen]] elements, or Group VIIa of the periodic table. It is also most reactive chemical element.  Flourine is so dangerous that it must be stored in steel containers, and even then it reacts with the steel. Fortunately the layer of flouride that is formed is unreactive, and prevents it from reacting further.  Under ordinary conditions, fluorine is a [[gas]] with a pale yellow color. <ref>[http://www.britannica.com/eb/article-9034677 ''Fluorine'']</ref>
