Helium is a chemical element that occurs in great abundance throughout the universe, although it is not as widely distributed on Earth. It typically takes the form of a gas, and it heads up the list of noble gases in the periodic table of elements. Like other noble gases, helium is extremely stable, and it does not readily form compounds with other elements. There are a number of uses for this gas, and it is widely considered to be a very useful and valuable element.
The atomic number of helium is two, making it the second lightest element. It is identified on the periodic table with the symbol He, and it is the least reactive of the noble gases. As a result, helium is one of the least reactive elements on Earth. Its extreme stability makes it a popular choice for a range of uses in situations where unstable materials are being handled, or where the use of other elements might be dangerous.
The discovery of helium occurred in 1868, when astronomers observed a strange band of light during a solar eclipse. The band of light did not correlate with any known element, and the observers realized that they had identified a new gas, which they called “helium” after the Greek Helios, for “Sun.” Within 30 years, scientists had succeeded in isolating and extracting the gas from the mineral clevite.
It was officially discovered in 1895 by two Swedish chemists, Per Teodor Cleve and Nils Abraham Langlet. Helium has a number of applications in the world today. This post will take you through some of the common uses of helium. The largest use of helium is in cryogenics. In fact, one of the most common uses of helium is in MRI machines. What Is an MRI Machine A magnetic resonance imaging, more commonly known as an MRI, machine is a device that uses a combination of radio waves and a magnetic field to view internal images of the body.
Although helium is the second most abundant element in the universe, it can be challenging to find on Earth. It is frequently extracted from natural gas, which can contain the element in concentrations ranging from 2 to 7%. The extremely stable, non-reactive gas became a vital tool during the First World War, when access to helium was highly restricted, and this occurred again during the Second World War. Many of the potential uses of the gas can be military in nature, including use as a non-reactive buffer for arc welding and as a lifting agent for balloons of all sizes. Helium is also used as a supercoolant in scientific experimentation and nuclear reactors.
Pure helium is not toxic, and exposure to the clear, odorless, and tasteless gas should not pose a health risk. However, excessive inhalation of the gas can be dangerous, as it will act as an asphyxiate. In addition, when inhaled directly from a pressurized tank, it may cause lung damage, and commercial helium such as that found in party balloons may be contaminated with other substances that are not healthy to inhale.
Hydrogen is the lightest and most common element in the cosmos. Its atomic number is 1. In its elemental state, hydrogen is rare. But it is one of the components of water and vital to life.
Common Uses of Hydrogen
It is primarily used to create water. Hydrogen gas can be used for metallic ore reduction. Chemical industries also use it for hydrochloric acid production. The same hydrogen gas is required for atomic hydrogen welding (AHW).
Electrical generators use the gas as a rotor coolant. The element is relied upon in many manufacturing plants to check for leaks. Hydrogen can be used on its own or with other elements. Other applications include fossil fuel processing and ammonia production. Ammonia is part of many household cleaning products. It is also a hydrogenating agent used to change unhealthy unsaturated fats to saturated oils and fats.
Hydrogen is also used for methanol production. Tritium is generated in nuclear reactions. It is a radioactive isotope used to make H-bombs. It can also be used as a luminous paint radiation source. Tritium is used in biosciences as an isotopic label.
Hydrogen and Fuel Cells
The element is often used as fuel because of its high calorific value. Combustion generates plenty of energy. Hydrogen fuel cells generate electricity from oxygen and hydrogen. These electrochemical cells generate only water vapor so it is considered as environment friendly.
Fuel cells are used in spacecrafts, remote weather stations and submarines. When in liquid form, it is used as rocket fuel. Deuterium is heavy hydrogen. This isotope is used for nuclear fusion reaction in nuclear reactors.
Use in Weather Balloons
Because hydrogen is light, scientists are able to use it with weather balloons. Meteorologists’ weather balloons have this element installed. These balloons are fitted with equipment to record information necessary to study the climate. During the First World War, these were utilized in balloon airships.
Industrial Applications
Other uses of hydrogen are in the fertilizer and paint industries. It is also used in the food and chemical industries. Food industries use the element to make hydrogenated vegetable oils such as margarine and butter. In this procedure, vegetable oils are combined with hydrogen. By using nickel as a catalyst, solid fat substances are produced.
In petrochemical industry, hydrogen is required for crude oil refinements.
Welding companies use the element for welding torches. These torches are utilized for steel melting. Hydrogen is required as a reducing agent in chemical industries. Chemical industries use them for metal extraction. For example, hydrogen is needed to treat mined tungsten to make them pure.

Chemical Compounds
One Use Of Helium Using
This element is used for producing several chemical compounds. Apart from ammonia, hydrogen can be harnessed in other ways. It can be used to make fertilizers, hydrochloric acids and an assortment of bases. The same element is required for methyl alcohol production. Methyl alcohol is used in inks, varnishes and paints. Hydrogen peroxide is another vital compound.
Hydrogen peroxide is used in many ways. First and foremost it is used for medication. It is included in most first aid kits. It is primarily used for treating wounds and cuts. Peroxide is also a toenail fungus disinfectant. Hydrogen peroxide can be diluted in water. It can kill bacteria and germs if used as whitewash. The same element can be used for teeth whitening and canker sores treatment.
Hydrogen peroxide can be used in non-medical ways. Other applications include a pest controller in gardens, removing stains on clothing and functioning as a bleaching agent for cleaning homes.
Hydrogen Production Methods
The element is produced in several ways. They can be harvested to be used as hydrogen fuel cells. It can also be generated via industrial processes. Other methods include bio hydrogen production, thermolysis or electrolysis. Hydrogen pinch and steam reforming are also used by many industries. The most common technique for harvesting the element is steam reforming.
One Use Of The Element Helium
Steam reacts with methanol to generate carbon monoxide and hydrogen. This process is done at high temperatures. When the temperature is set down, carbon monoxide will be produced. It can produce carbon dioxide and hydrogen. The efficiency rate is around 75%. Pinch is another technique.
This method moves the element through the hydro cracking sections. The objective is to produce the final procedure so no more hydrogen is emitted. Any hydrogen generated is stored. They are used for other means.
Thermolysis and Electrolysis
These are used for hydrogen production for industrial uses. The method is also known as water splitting. In this method, hydrogen and oxygen molecules are separated using electric currents. Heat is not necessary for electrolysis.
However, high temperatures will produce better hydrogen yields. Sometimes urine is used in lieu of water. Many uses of hydrogen rely on this method.
There is also bio hydrogen. The element it produces is useable. The process includes electrohydrogenesis, enzyme reactions and fermentation. With fermentation, biological materials are destroyed.
