Arsenic
Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however.[6] Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon -

Phosphorus
Phosphorus is one of the essential nutrients for plants, animals and humans - to put it simply without phosphorus, life would not exist. Within plants, P is essential to cell development and structure, reproductive and enzyme balance and within animals for bone development, cell structure, reproduction etc. There is no substitute for P, and there never will be. -
Antimony
Around 50% of pure antimony currently produced is used for hardening lead, to make alloys which are then used (mostly) in batteries. However, the hardened alloy also finds use in small arms bullets (and tracer rounds) and cable sheathing among others. Whilst too brittle to be of use in its pure form, antimony makes an excellent alloying material for other metals, providing increased hardness and mechanical strength -
Platinium
Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. -
Nickel
About 6% of world nickel production is still used for corrosion-resistant pure-nickel plating. Nickel was once a common component of coins, but has largely been replaced by cheaper iron for this purpose, especially since the metal is a skin allergen for some people. It was reintroduced into UK coins in 2012 despite objections from dermatologists.[4] -
Nitrogen
This element is present in virtually all pharmacological drugs. In the form of nitrous oxide it is used as an anesthetic. Cryopreservation also uses the gas to conserve egg, blood, sperm and other biological specimens. The CPUs in computers use the gas to keep them from heating up. X-ray detectors also rely on this element -
Chlorine
Chlorine has a huge variety of uses; as a disinfectant and purifier, in plastics and polymers, solvents, agrochemicals and pharmaceuticals, as well as an intermediate in manufacturing other substances where it is not contained in the final productChlorine is used worldwide to purify water supply as the ultimate defense against waterborne microbiological infection. Modern day cholera epidemics in Peru, China, India or Africa exemplify the devastating consequences of poor sanitation. . -
Oxygen
This gas is used in various industrial chemical applications. It is used to make acids, sulfuric acid, nitric acid and other compounds. Its most reactive variant is ozone O3. It is applied in assorted chemical reactions. The goal is to boost reaction rate and oxidation of unwanted compounds. Hot oxygen air is required to make steel and iron in blast furnaces. Some mining companies use it to destroy rocks. -
Aluminum
Despite its prevalence in the environment, aluminium salts are not known to be used by any form of life. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals.[6] Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest. -
Flourine
While a few plants and bacteria synthesize organofluorine poisons, fluorine has no metabolic role in mammals. The fluoride ion, when directly applied to teeth, reduces decay; for this reason, it is used in toothpaste and water fluoridation. A significant fraction of modern pharmaceuticals—such as atorvastatin (Lipitor) and fluoxetine (Prozac)—contain fluorine.Even more hydrogen fluoride is used to make organic fluorides. These compounds have have very high chemical and thermal stability; their l -
Argon
Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily non-reactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon gas also has uses in incandescent and fluorescent lighting, and other types of gas discharge tubes. Argon makes a distinctive blue-green gas laser. -
Hellium
Evidence shows that the human voice can be changed with a bit of helium. The gas is also used as light weight aircraft fuel. The element is usually combined with hydrogen in air balloons. Hydrogen alone is fine, but helium makes the balloon safer to use. The same gas is used by caisson workers too. Divers use oxygen and helium during their dives. The combination provides them with the atmosphere necessary to survive in high pressure environments. -
Radium
In nature, radium is found in uranium ores in trace amounts as small as a seventh of a gram per ton of uraninite. Radium is not necessary for living organisms, and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity. -
Krypton
rypton, like the other noble gases, can be used in lighting and photography. Krypton light has a large number of spectral lines, and krypton's high light output in plasmas allows it to play an important role in many high-powered gas lasers (krypton ion and excimer lasers), which pick out one of the many spectral lines to amplify. There is also a specific krypton fluoride laser. The high power and relative ease of operation of krypton discharge tubes caused (from 1960 to 1983) the official length -
Neon
Its most common application is in advertisement. Ne generates a bright reddish orange color. Neon lights refer to various colors and lights. However, neon lights come from other gases and not necessarily neon.The element is also used in helium neon lasers, television tubes and wave meter tubes. It is also used in lightning arresters. This is used to shield electrical equipment from lightning. There are also high voltage indicators and vacuum tubes that employ it. -
Polonium
Polonium can be used to eliminate static electricity in machinery that is caused by processes such as the rolling of paper, wire or sheet metal, although other materials which emit beta particles are more commonly used for this purpose. Polonium is also used in brushes for removing dust from photographic films, although the polonium must be carefully sealed to protect the user from contamination. Polonium is also combined with beryllium to form neutron sources. -
Actinium
A soft, silvery-white radioactive metal, actinium reacts rapidly with oxygen and moisture in air forming a white coating of actinium oxide that prevents further oxidation. As with most lanthanides and actinides, actinium assumes oxidation state +3 in nearly all its chemical compounds. -
Radon
Unlike all the other intermediate elements in the aforementioned decay chains, radon is gaseous and is thus easily inhaled. Thus, even in this age of nuclear reactors, naturally-occurring radon is responsible for the majority of the public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Despite its short lifetime, some radon gas from natural sources can accumulate to far h -
Francium
Due to its rarity and instability francium is used for research purposes only. It is a heavy, unstable, radioactive metal with a maximum half-life of 22 minutes and a low melting point (27 degrees Celsius, 87 degrees Fahrenheit) and, if enough of it is accumulated, it would be liquid in a warm room. -
Americium
It is widely used in commercial ionization chamber smoke detectors, as well as in neutron sources and industrial gauges. Several unusual applications, such as a nuclear battery or fuel for space ships with nuclear propulsion, have been proposed for the isotope 242mAm, but they are as yet hindered by the scarcity and high price of this nuclear isomer. -
Dubnium
Little is known about the element and it has no known uses. Dudnium is a synthetic element and therefore is not naturally found in the environment. The discovery of Dubnium was made independently by Russian researchers at the Joint Institute for Nuclear Research in 1967 and then by American researchers at the University of Califorinia, Berkeley in 1970. Dubnia is named after Dubna, Russia, where it was first discovered. -
Plutonium
Plutonium-238 has a half-life of 88 years and emits alpha particles. It is a heat source in radioisotope thermoelectric generators, which are used to power some spacecraft. -
Ununbium
While not much is known about the chemical characteristic of ununbium, it is predicted to have similar chemical properties to mercury; for this reason ununbium is sometimes referred to as eka-mercury. There are no known commercial uses of ununbium at this time. -
