Boron Facts
Boron (B) is a black, semi-metallic element with an atomic number of five and five protons in the nucleus. Its compounds have been used for thousands of years, but the element itself was not isolated until the early nineteenth century.
Interesting Boron Facts:
Sir Humphry Davy, Joseph-Louis Gay-Lussac, and Louis Jaques Thenard isolated the boron element by creating a reaction of boric acid with potassium in 1808.
Boron is fairly rare in the solar system and makes up only 0.001% of the Earth's crust, but its naturally occurring compounds are quite common.
Some common compounds of boron are borax, boric acid, colemanite, kernite, ulexite, and borates.
Pure boron is extremely difficult to produce, even in laboratory conditions, because of its propensity to join with carbon.
Historically, borax glazes have been used by far-reaching cultures as early as AD300.
Eighteenth century Florentines used it for medical purposes as sal sedativum.
Boron is fairly hard, and together with carbon and nitrogen forms a superhard and highly heat-resistant compound commonly called heterodiamond.
Boron has two naturally occurring stable isotopes, 11B (80.1%) and 10B (19.9%), which are commonly used in a number of industries.
Both 10B and 11B possess nuclear spin, with the spin of 10B being 3 and that of 11B being 3/2.
Boron is present in over 100 minerals on Earth but is difficult to prepare or study.
Biologically, boron is present in the cell walls of plants and is therefore present in all foods made from plants.
There is a boron-based natural antibiotic called boromycin, a derivative of streptomyces.
Boron is used in a number of well-known cleaning agents in the compound form borax.
Another compound, boric acid, is lethal to insects but not harmful to mammals, and is therefore used in pesticides.
