Although Hydrogen is the most basic and least dense element in the periodic table, it is incredibly powerful.
It’s the primary fuel for stars, including our sun, where nuclear fusion transforms hydrogen into helium, releasing immense energy.
Additionally, hydrogen’s potential as a clean energy source is paving the way for innovative technologies, from fuel cells to sustainable energy solutions.
The most prevalent element in the universe, Hydrogen, makes up the majority of all stuff. Stars, automobiles, and rocket ships can all be propelled by this potent substance.
Look at these fascinating hydrogen facts to learn more about this essential element.
Interesting Hydrogen Facts
The Majority of The Universe’s Matter Is Hydrogen
One of the most important hydrogen facts is that a significant fraction of all ordinary matter in the universe is made up of hydrogen.
Hydrogen makes up around 75% of ordinary matter by bulk and more than 90% by number. It is also found in most stars, molecular clouds, and gas giants.
Hydrogen Occurs in The Universe as A Plasma
Yet, on Earth, Hydrogen usually only appears as a gas or in combination with other elements.
Although so prevalent, the diatomic gaseous form of Hydrogen (H2) is scarce in our environment. In the air we breathe, gaseous Hydrogen only accounts for 0.00005 percent.
The Three Isotopes of Hydrogen
There are three isotopes or variations of Hydrogen that are found in nature. Protium, Deuterium, and Tritium are the names of the three isotopes of Hydrogen, the only element whose isotopes have unique names.
These atoms are isotopes because they all have the same amount of protons but have different numbers of neutrons.
One of These Isotopes Is Radioactive
Protium, often known as hydrogen-1, is the isotope of Hydrogen found in the greatest amount (around 99.98%).
The molecular symbol for this stable isotope is 1H. With just a single proton and electron, it is the most basic of all the elements.
Since just one proton is in its nucleus, protons receive their name. Hydrogen is the only element that may exist in a stable state without a neutron, which is equally important to note.
Properties of Deuterium
Deuterium, often known as hydrogen-2, is one of the two stable isotopes of Hydrogen. One proton and one neutron comprise its nucleus, and its molecular symbols are 2H or D.
In 1931, American chemist Harold Urey made the discovery of deuterium. From the Greek word deuterons, which means “second,” Urey named the element deuterium.
These two particles make up its nucleus. This isotope is frequently referred to as “heavy hydrogen.”
Characteristics of Tritium
Tritium, also known as hydrogen-3, is the third isotope of Hydrogen and has a nucleus of one proton and two neutrons. Its identifiers are 3H or T.
The half-life of the radioactive isotope tritium is 12.32 years. When cosmic rays and atmospheric gases interact, it happens spontaneously.
Heavier Isotopes of Hydrogen
There are heavier isotopes of Hydrogen as well, but these are artificial and do not naturally exist.
Hydrogen-7 (7H), one of these artificial isotopes, has the shortest half-life of any currently understood isotope.
Hydrogen is an important resource since it has numerous industrial applications for all three isotopes.
It is necessary for the creation of ammonia, which is used as a fertilizer for plants, and it also has use in the processing of metals and fossil fuels, among others.
Hydrogen Lives as A Compound
Hydrogen must be separated from the other elements because it primarily lives on Earth as compounds with other elements like water or methane (CH4).
Industries must manufacture Hydrogen in this way using processes like electrolysis, gasification, or steam reforming.
These techniques produce the useable H2 molecules by separating the components of diverse substances.
Hydrogen Once Used in Airships
Hydrogen, the lightest chemical in the periodic table, weighs 14 times as little as air. It can therefore raise items, much as helium can lift balloons.
Early airships employed Hydrogen as a lifting gas since it is more affordable and accessible than helium. Even the heaviest airships, like the German zeppelin Hindenburg, were lifted by Hydrogen.
High Combustibility of Hydrogen
It became an unsafe lifting gas for manned airship missions as a result. Airships, including hydrogen-filled airships, eventually lost popularity, notably after the Hindenburg caught fire in 1937.
Hydrogen Fuels Stars Like the Sun
The fact that Hydrogen powers the Sun and other stars is arguably one of the most well-known hydrogen facts.
Like most stars, the Sun’s core is composed of hydrogen atoms, which are fusion-bonded under intense pressure.
The Sun’s nuclear fusion process generates the heat and light it radiates, which fuels most of Earth’s life.
In addition, heavier chemical elements are eventually produced due to atomic fusion in stars’ cores.
In essence, hydrogen is responsible for the emergence of many elements heavier than lithium-7 in the universe. You probably wouldn’t be here without it.
Role of Hydrogen in Human Space Exploration
Although hydrogen has its share of risks and mishaps, it also allows us to travel to other planets.
When it comes to refueling spacecraft, liquid hydrogen is the best option because it is a lightweight material with a lot of power.
When combined with liquid oxygen, it can offer the most effective energy source for space flight.
Humans could explore space and even complete the well-known Apollo missions thanks to hydrogen fuel.
Uses of Liquid Hydrogen
Liquid hydrogen storage does present a special set of difficulties. For instance, the hydrogen must be at or below -423 °F (-252.78 °C; 20.37 K) to maintain its liquid state.
This necessitates extensive insulation and other safety precautions. As a result, NASA bragged that controlling liquid hydrogen was one of its greatest technological triumphs.
Hydrogen Fuel in Vehicles
One of the world’s most environmentally friendly fuels is hydrogen. Hydrogen does not require or emit carbon dioxide, contributing to global warming because it rapidly reacts with oxygen to create water and release energy.
Hydrogen fuel, a green energy source that can replace fossil fuels, has found industry use. Hydrogen fuel cells are widely used in fuel cell cars and buses to travel the roadways.
Although hydrogen fuel is a possible replacement for fossil fuels, practical issues with hydrogen production and containment still exist.
Liquid hydrogen requires specialized containers with good insulation to maintain its liquid state.
Hydrogen Ions Determine Acidity or Basicity
An aqueous chemical can be neutral, basic, or acidic depending on its pH. A solution’s concentration of H+ ions (hydrogen atoms with positive electric charges) is indicated by the word “pH,” which stands for “potential of hydrogen” or “power of hydrogen.”
Lower pH is caused by more H+ ions in the solution. A solution is considered acidic if its pH is less than 7. Conversely, a pH greater than 7 denotes an alkaline or basic solution.
Hydrogen Can Behave Like a Metal
Although not a metal, hydrogen can exhibit metallic characteristics under certain circumstances; when hydrogen is exposed to extremely high pressures and temperatures, metallic hydrogen results.
In particular, it must be at pressures of at least 25 GPa (3,600,000 psi; 250,000 atm). Hydrogen is present in this phase as a liquid and behaves like metallic components as an electrical conductor.
The invention of Metallic Hydrogen by Hillard B.H and Eugene W
In 1935, physicists Hillard Bell Huntington and Eugene Wigner first predicted that metallic hydrogen would exist.
Metallic hydrogen is famously challenging to generate in laboratories due to its high pressures to exhibit metallic features.
Scientists hypothesize that the inner regions of the gas giants Jupiter and Saturn contain significant amounts of metallic hydrogen.
Several planets outside of our solar system may contain metallic hydrogen.
