Boron deficiency is a pathology which may occur in animals due to a lack of boron.A report given by E. Wayne Johnson et al. at the 2005 Alan D. Leman Swine Conference [1] suggests that boron deficiency produces osteochondrosis in swine that is correctable by addition of 50 ppm of boron to the diet.

Between 2001 and 2022, suicide rates actually increased significantly for men and women over 55, while it declined for those age 15 to 34. Making sense of the statistics.
Boron is an essential element for plant growth and is frequently used as a fertilizer, however in large concentrations boron can be toxic, and therefore boron is a common ingredient in herbicides and insecticides. Boron is also found in chemicals used to treat wood and as protective coatings and pottery glazes. [20]
Unlike silicates, boron minerals never contain boron with coordination number greater than four. A typical motif is exemplified by the tetraborate anions of the common mineral borax , shown at left. The formal negative charge of the tetrahedral borate center is balanced by metal cations in the minerals, such as the sodium (Na + ) in borax . [ 1 ]
Boron trifluoride is the inorganic compound with the formula BF 3. This pungent, colourless, and toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds.
Boron is added to boron steels at the level of a few parts per million to increase hardenability. Higher percentages are added to steels used in the nuclear industry due to boron's neutron absorption ability. [citation needed] Boron can also increase the surface hardness of steels and alloys through boriding.
The boron atom in BH 3 has 6 valence electrons. Consequently, it is a strong Lewis acid and reacts with any Lewis base ('L' in equation below) to form an adduct: [7] BH 3 + L → L—BH 3. in which the base donates its lone pair, forming a dative covalent bond. Such compounds are thermodynamically stable, but may be easily oxidised in air.
