Fluoride not flouride

As if you could take flour on a ride.

Here’s the answer to my last blog, 4th August 2012

A bonding diagram for the formation of lithium fluoride

Lithium fluoride contains lithium ions, Li+ and fluoride ions, F- bonded ionically.

lithium fluoride, LiF

When atoms react they gain the electron arrangement of the nearest noble gas in The Periodic Table and hence become more stable.

The lithium ion has an electron arrangement the same as the noble gas helium and the fluoride ion has the same electron arrangement as neon.

So what is The Periodic Table and what are the electron arrangements of the noble gases?
