Nitrogen

Description:

Nitrogen is a inert diatomic gas at standard conditions. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates, and cyanides, contain nitrogen. It occurs in all living organisms, and the nitrogen cycle describes movement of the element from air into the biosphere and organic compounds, then back into the atmosphere. It is a constituent element of amino acids and thus of proteins and nucleic acids. It resides in the chemical structure of almost all neurotransmitters, and is a defining component of alkaloids, biological molecules produced by many organisms.

The rare earth element Cerium

Not many of us are familiar with the element Cerium. Cerium is an element used in flat television screens and compact discs and such important electronic devices. Let us find out more about this element...

Everyday Chemistry - Meet Cerium: The Rare Earth Element
Wondering what Cerium is? You might have never heard of it but you have most definitely seen it! It is an element used in flat television screens, CDs and important electronic devices. Scroll to know more!
Birthday - Cerium was born in the year 1803. It was named after an asteroid Ceres by Von Hisinger and Berzelius.
Basic Info - Cerium is called a rare earth metal. But ironically, it is more abundant on earth than copper and lead. As an element, cerium does not have any uses. This is because it tarnishes easily and is very reactive with water. It will also ignite if simply scratched with a knife. Its compounds, however, are very useful.
Uses - It is non-toxic and can be used to reduce particulate emissions from diesel combustion engines and help people who suffer from asthma and bronchitis. It is also used to make electronic appliances such as flat-screen TVs, low energy light bulbs and compact discs.
Periodic Table - Cerium is present in the periodic table in a group called the Lanthanides. Its atomic number is 58, which means it has 58 protons in its nucleus and 58 electrons surrounding the nucleus

The Brighter Side - This element has lot of potential and will soon be used widely. This is mainly because it can be used to reduce particulate emissions from diesel combustion engines and it helps to produce a safe red dye, which can be used in paints.

Chemical properties - Lithium symbol, electronic configuration, density

Beryllium Description: Beryllium is a divalent element which only occurs naturally in combination with other elements in minerals. It is primarily used as a hardening agent in alloys, notably beryllium copper. In structural applications, high flexural rigidity, thermal stability, thermal conductivity and low density make beryllium a quality aerospace material for high-speed aircraft, missiles, space vehicles and communication satellites. 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. Chemical Properties.

Lithium Description: Lithium is a metal that belongs to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, high strength-to-weight alloys used in aircraft, lithium batteries and lithium-ion batteries. Lithium niobate is used extensively in telecommunication products such as mobile phones and optical modulators, for such components as resonant crystals. Lithium is also used in the pharmaceutical and fine-chemical industry in the manufacture of organolithium reagents, which are used both as strong bases and as reagents for the formation of carbon-carbon bonds. Organolithium compounds are also used in polymer synthesis as catalysts/initiators in anionic polymerization of unfunctionalized olefins. Lithium compounds continue to be the gold standard for the treatment of bipolar disorder and are helpful for related diagnoses, such as schizoaffective disorder and cyclic major depression.
