Boron has some 15 different isotopes of which 13 are radioisotopes and are unstable. The remaining two of them Boron-10 and Boron-11 are stable isotopes. They are naturally occurring isotopes. Boron-10 has a natural abundance of 19.9% while Boron-11 has 80.1% abundance. Both of them have the same number of protons 5, 5 each, and electrons. While Boron-10 has 5 neutrons and Boron-11 has 6 neutrons. This makes them differ.
Which is the electron configuration for boron?
The electronic configuration of Boron is 1s2, 2s2, 2p1. 2 electrons are 1s orbital, the other two are in 2s orbital while the remaining one is in 2p orbital.
Where is boron found?
It is a very rare metal in the universe as well as in the solar system because it was produced in a very small amount during the time of the Big Bang. It could be found in meteoroids and space dust. About 0.001% of boron can be found in the Earth's crust in the form of borate minerals. Turkey is the largest producer of Boron products then America is the second producer. 72% of the world's known deposits are in Turkey. Some 23% of boron are produced from U.S. Borax Boron Mine.
