19.8%, so about 20%. Again, there are only two naturally occurring isotopes. The mass of boron-10 is 10.01294 and the mass of boron-11 is 11.00931. You can use the atomic mass of boron to calculate the relative abundance of boron-10.
because its half life is stable, therefore the decay pathway does not exist. Boron has two naturally occurring and stable isotopes, 11B (80.1%) and 10B (19.9%). Boron 10 and Boron 11 have neither a decay pathway or a half life because of this once again. There are 13 known isotopes of boron, the shortest-lived isotope is 7B which decays through proton emission and alpha decay. It has a half-life of 3.5×10−22 s.
is a compound involving boron) are used in the manufacture of fiberglass insulation and sodium perborate bleach. Boric acid (H3BO3) is used to manufacture textile fiberglass and is used in cellulose insulation as a flame retardant. Borax (Na2B4O7·10H2O) is used in laundry products and as a mild antiseptic. Other boron compounds are used to make borosilicate glasses, enamels for covering steel and as a potential medicine for treating arthritis.
shielding and in boron neutron capture therapy. People take boron supplements as medicine. Used for building strong bones, treating osteoarthritis, as an aid for building muscles and increasing testosterone levels, and for improving thinking skills and muscle coordination. Women sometimes use capsules containing boric acid, the most common form of boron, inside the vagina to treat yeast infections. People apply boric acid to the skin as an astringent or to prevent infection; or use it as an eye wash. Used as a food preservative between 1870 and 1920, and during World Wars I and II. Affects the way the body handles other minerals such as magnesium and phosphorus. Increases estrogen levels in older women and healthy men. Estrogen is thought to be helpful in maintaining healthy bones and mental function. Boric acid can kill yeast that cause vaginal infections.
fruit such as grapes and pears, green leafy vegetables and beans are good sources of Boron. Boron helps regulate body’s use of calcium, phosphorus, and magnesium. Helps prevent abnormalities in growth. Taking high dosages for a long time can lead to reduced fertility for men! Also enhances brain function and even memory!
