Discovered in 1808 by Sir Humphry Davy, Gay-Lussac, and Thernard. It was discovered in England and France.

Appearance
Boron's melting point is 2079 degrees celcius. (I recieved mixed results on melting and boiling points) Its boiling point is 2550 degrees celcius. It;s mass is 10.81. AMU It has three oxidations states. It has an atomic radius of 83 pm. It's electron configuration is (He)2s(second)2p Boron transmits portions of infared. It is a poor conductor of electricity at room temperature but is a good conductor at high temperatures. Boron is a metalloid. Boron is black, hard, and brittle. It has a tetragonal lattice form.

Uses
It is used in Pyrotechnic flares to create a green color and is used as an igniter in rockets. A compound with boron in it is used to make insulation fiberglass and sodium perborate bleach Boron is also used to control nucleur reactors, as a shield from nucleur radiation, and in a device used to detect neutrons. Boron nitride can be used to make material hard like diamonds.

Where it can be found and how much it costs
Cryshous crystalline boron, which is 99% boron, costs $5/g. Amorphous boron costs $2/g Boron does not occur naturally but can be found in some orthoboric acids found in volcanic spring water. Boron is also found in a few minerals, but is primarily found in rasorite which is found in the Mojave Desert. Boron has two isotopes. Boron-10 19.78% and boron-11 80.22%
