ScienceDirect ® is a registered trademark of Elsevier B.V. Hyperfine structure of atomic fluorine (F I). Nearly 500 years ago it was discovered that fluorite (then called fluorspar) would melt and flow when in a fire - it became an additive that made it easier for blacksmiths to work molten metal. Many materials adopt the same atomic arrangement as Fluorite and this structure type is fundamental in our understanding of their properties - many fluorites give off light i.e. PLAY.
