Question

How does hydrogen occur in nature? What is another name of hydrogen?

Answer 1

The chemical element hydrogen has the symbol $H$ and the atomic number $1$. Hydrogen is the lightest element in the periodic table, with an atomic weight of $1.008$. Hydrogen is the most common chemical element in the universe.

Complete answer:
The simplest element is hydrogen. Each hydrogen atom has only one proton. Hydrogen is also the universe's most abundant element. The sun, for example, is largely made up of hydrogen. The sun is simply a massive gaseous mixture of hydrogen and helium.
Water is the most common form of hydrogen on the planet. Water (${H_2}O$) has two hydrogen atoms and one oxygen atom in each molecule. Hydrogen can also be found in a wide variety of rocks and minerals. It has a concentration of about $1,500$ parts per million. Hydrogen is the tenth most prevalent element in the Earth's crust as a result of this.
Hydrogen is also found in trace amounts in the Earth's atmosphere. Because of its low density, hydrogen is not common in the atmosphere. The gravity of the Earth cannot hold hydrogen atoms in place very well. They effortlessly float away towards space.
Hydrogen is known to have three isotopes. The mass numbers of hydrogen’s isotope are $1,2$ and $3$ the most abundant is mass $1$ isotope generally called hydrogen. There are three naturally occurring hydrogen isotopes: protium, deuterium, and tritium, Hydrogen is also called protium. The lighter isotope of hydrogen is known as protium, but it has no chemical symbol other than $^1H$.
Hydrogen is generally found as diatomic hydrogen gas ${H_2}$, or it combines with other atoms in compounds—monatomic hydrogen is rare. The $H - H$ bond is one of the strongest bonds in nature,

Note:
In the presence of sunshine, a flame, or a spark, hydrogen, the lightest element, will explode at concentrations ranging from $4 - 75$ percent by volume. Despite its stability, hydrogen forms a wide range of bonds and is found in a wide range of compounds.
