Wikipedia article:  Nitrogen

 

Nitrogen

 

Nitrogen (100)

 

·         Nitrogen ( /ˈnaɪtrɵdʒɨn/ ny-trə-jin) is a chemical element that has the symbol N, atomic number of 7 and atomic mass 14.00674 u.

 

·         Elemental nitrogen is a colorless, odorless, tasteless, and mostly inert diatomic gas at standard conditions, constituting 78.08% by volume of Earth's atmosphere.

 

·         Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen.

 

·         The extremely strong bond in elemental nitrogen dominates nitrogen chemistry, causing difficulty for both organisms and industry in breaking the bond to convert the N2 into useful compounds, but at the same time causing release of large amounts of often useful energy when the compounds burn, explode, or decay back into nitrogen gas.

 

·         Nitrogen occurs in all living organisms, and the nitrogen cycle describes movement of the element from the air into the biosphere and organic compounds, then back into the atmosphere.

 

·         Nitrogen is formally considered to have been discovered by Daniel Rutherford in 1772, who called it noxious air or fixed air.

 

·         Chaptal's meaning was that nitrogen gas is the essential part of nitric acid, in turn formed from saltpetre (potassium nitrate), then known as nitre.

 

·         Other classes of nitrogen anions (negatively charged ions) are the poisonous azides (N− 3), which are linear and isoelectronic to carbon dioxide, but which bind to important iron-containing enzymes in the body in a manner more resembling cyanide.

 

·         Other notable nitrogen-containing drugs are drugs derived from plant alkaloids, such as morphine (there exist many alkaloids known to have pharmacological effects; in some cases, they appear natural chemical defenses of plants against predation).

Wikipedia article:  Beryllium

 

Beryllium

 

Beryllium (100)

 

·         Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl.

 

·         Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation; therefore, it is the most common window material for X-ray equipment and in particle physics experiments.

 

·         The high thermal conductivity of beryllium and beryllium oxide have led to their use in heat transport and heat sinking applications.

 

·         Beryllium has exceptional flexural rigidity (Young's modulus 287 GPa) and a reasonably high melting point.

Wikipedia article:  Lithium

 

Lithium

 

Lithium (100)

 

·         Like all alkali metals, lithium is highly reactive and flammable.

 

·         When cut open, lithium exhibits a metallic luster, but contact with moist air corrodes the surface quickly to a dull silvery gray, then black, tarnish.

 

·         Because of its high reactivity, lithium never occurs free in nature, and instead, only appears in compounds, which are usually ionic.

 

·         Lithium occurs in a number of pegmatitic minerals, but due to its solubility as an ion is present in ocean water and is commonly obtained from brines and clays. (more…)

Wikipedia article:  Helium

 

Helium

 

Helium (100)

 

·         Helium is the second lightest element and is the second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined.

 

·         This is due to the very high binding energy (per nucleon) of helium-4 with respect to the next three elements after helium.

 

·         In 1903, large reserves of helium were found in natural gas fields in parts of the United States, which is by far the largest supplier of the gas today.

 

·         Helium is used in cryogenics (its largest single use, absorbing about a quarter of production), particularly in the cooling of superconducting magnets, with the main commercial application being in MRI scanners.
