Answer 1

Defination :-

Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element in the periodic table. At standard conditions hydrogen is a gas of diatomic molecules having the formula H₂. It is colorless, odorless, non-toxic, and highly combustible

Formula :-

H2

Making process :-

• Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. ...

• Electrolysis: An electric current splits water into hydrogen and oxygen.

Importance :-

The most important function of hydrogen in the human body is to keep you hydrated. Water is made up of hydrogen and oxygen and is absorbed by the cells of the body. Therefore, it is a crucial element which is used not in our body but also as a fuel, in military weapons .

Answer 2

Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element in the periodic table. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.[7][note 1] Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons.
