In the "word" BF4 the B stands for"Brent" aka Brett, the F stands for "FAV-RA" aka. Favre, the 4 stands for the number "Brent FAV-RA" wears. Brett Favre (BF4) was born on October 10, 1969. Brett Favre is 40 until Oct. 10, 2010 when he turns 41, hopefully not playing football, especially for the hated Minnesota "Viqueens". In 2011 Favre will turn 42 and so on.
Go Packers. I now do not miss Brett Favre because he supposedly wanted revenge on Ted Thomson. It's not Ted's fault that Brett himself waits until the preseason to ask to come back after A-Rodg is all warmed up to play football. Ted Thomson still is stupid.
Yes! BF4- is a tetrahedral as it is just a boron with four Florines attached and no lone pairs.

Not sure what the word isobal might be. BH4- and NH4+ are isoelectronic. BF4- and NH4+ are both tetrahedral and have the same geometry.
The BF4- ion, also known as tetrafluoroborate, is a polyatomic anion consisting of one boron atom and four fluorine atoms. Boron is at the center, surrounded by the four fluorine atoms, resulting in a trigonal bipyramidal structure with a formal negative charge on the ion.
Boron in BF4 has an empty p orbital, so it undergoes sp3 hybridization. The boron atom will promote its 2s and two of its 2p orbitals to create four sp3 hybrid orbitals, allowing the boron to form four sigma bonds with the surrounding fluorine atoms.
How well your PC will perform running BF4 COD Ghosts and Dayz depends on the type of PC you have and the specs of that PC.
Boron trifluoride BF3 reacts with F- ion to form the BF4- ion. BF3 has only 6 electrons around the B atom, is planar, and is a Lewis acid (as it will accept electrons from an electron pair donor such as F-. BF4- is a tetrahedral ion- all four bonds are equivalent.

BF4 (boron trifluoride) and Sr (strontium) yield SrF2 (strontium fluoride) when they react together. This reaction involves the exchange of ions between the compounds, resulting in the formation of strontium fluoride.

IGN Daily Fix - 2009 Walking Dead S2 and BF4 DLC Coming Soon was released on: USA: 29 October 2013
The electron pair geometry for BF4- is tetrahedral. There are four regions of electron density around the boron atom, consisting of three bonding pairs and one lone pair, leading to a tetrahedral arrangement.
