The element boron, not to be confused with Borax or boric acid, is an essential trace mineral for human health, helping to strengthen bones, increase absorption of other minerals, and to regulate the sex hormones in both men and women. Intake of boron helps the body absorb and utilize other minerals by interacting with steroid hormones. Boron is important for bone growth and maintenance as it reduces the urinary excretion of magnesium and calcium. The boron vertebrate transporter helps these substances deposit within the bones rather than being excreted as waste. Higher levels of magnesium and calcium help prevent osteogenesis, or brittle bones (that can break easily,) which is especially important in postmenopausal women and older men, as a deficiency in these minerals has a negative effect on bone strength and regeneration.…
In case some of you guys didn’t know valadium is a metal and its always fun to learn something new. Also the symbol of this element would be the letter “v”.…
3.1.1.1.1. Properties Rests symbols plays a fundamental role in the symbolic time axis, and they could be inserted between notes or at the end of a musical passage. For this reason, the total symtime duration of a theme is not always equal to the sum of the note duration, so the total symtime duration is an additional property associated to a theme. Other important property associated to a theme is the total number of elements (i.e., rows). Properties of a theme are denoted using the dot symbol, i.e., theme.duration , theme.rows.…
Chlorobium tepidum is a thermophile and also an anaerobic phototrophic bacterium. The cells of this bacterium are gram-negative non-motile rods of varying lengths that photooxidize reduced sulfur compounds. This bacterium can be found in anoxic and sulfide-rich waters, mud, sediments, microbial mats, and even microbial consortia.…
1. In our notes, we reviewed the Major mineral: Sodium. We know from news and health professionals, our intake of sodium is well over recommendations for our bodies need. List three specific changes you could make to your diet to decrease your sodium intake. • Eat more fresh fruit and vegetables since they are low in sodium.…
The Periodic Table by Primo Levi was very interesting. You could really tell that he had a deep fascination with chemistry. He relates what happens in his life to the chemical elements. Each chapter of the book is named after a chemical element in the periodic table and he relates all of his life. He doesn’t seem to be able to separate his work life and personal life.…
Silver, also known as white metal, has been used for many years in jewellery and coins and was a symbol of wealth and prestige. But today, silver's primary use is industrial because it resists corrosion and oxidation. New innovations like cell phones or solar panels are constantly emerging to take advantage of silver's unique properties. Silver is a precious metal because it is rare and valuable. It's non-toxic, antimicrobial qualities make it useful in medicine and pharmaceutical products.…
One of the toxic heavy metals that have been of major environmental concern in waste water treatment is Chromium. Chromium is an essential nutrient for plant and animal metabolism. However, the increasing accumulation of chromium in the environment from industrial outputs has caused great concern. Chromium contaminated wastewater originates from dyes and pigments manufacturing, wood preserving, electroplating and leather tanning industries. In India, nearly 80% of tanneries engaged in chrome tanning process.…
Chromium is a transitional metal. It is a stiff, silvery metal that when polished can have a mirror shine. Most of the chromium is found South Africa, India, Kazakhstan and Turkey as chromite. Some uses for chromium are to harden steel and make stainless steel. Chromium can be used for coloring, and chromium makes rubies red.…
Phosphorus is the fifteenth element on the periodic table. It has fifteen protons, sixteen neutrons, and fifteen electrons. It has a mass number of 30.97 and an atomic number of fifteen. Its element symbol is “P.” Phosphorus was discovered by Hennig Brandt in Hamburg in the year 1669. Hennig evaporated urine and heated the residue left behind until it was red hot.…
In 1817 a scientist known by the name of Johann August Arfvedson discovered a new element called lithium while he was working with a mineral petalite (Jefferson Lab Web). However, even though this element was found by Arfvedson, William Thomas Brande and Sir Humphrey Davy were the first people to isolate it (Jefferson Lab Web). Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project).…
The discovery of Arsenic is credited to the German philosopher Albertus Magnus, approximately in the year 1250. The exact location of this discovery however, is unknown. In his work “De Mineralibus”, he described how Arsenic could be obtained through the heating of orpiment and soap together. This notorious poison has been used by the Egyptians, Greeks, and Chinese for centuries as well. Arsenic can be found abbreviated as “Ar” in group 15, period 4.…
Chromium Hexavalent Compounds are produced in the productions of metals and are commonly found in factories. Chromium Hexavalent is an unnatural, man-made, corrosive element. “Elemental chromium does not occur naturally in the environment. The divalent (chromous) state is readily oxidized to the more stable trivalent (chromic) state. Although the hexavalent state (including chromates) is more stable than the divalent state, it is rarely found in nature.…
On earth, selenium is commonly found in trace amounts of soil, sedimentary rocks, and is picked up throughout the process that concentrates copper and other metals. Selenium is a dietary supplement and is nutritionally essential for humans thats component with more than two dozen selenoproteins, which plays critical roles in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from oxidative damage and infection.…
My name is Platinum. My name comes from the Spanish word “platina”, which translates into “little silver”. I am a transition metal, and I am found in ground 10, period 6 in the periodic table. I am also part of the platinum-group metals, or PGMs, along with ruthenium, rhodium, palladium, osmium, and iridium.…
