Why is hydrogen H2 and not just H?
When two hydrogen atoms come together, it results in formation of a hydrogen molecule with two electrons in the outermost shell. Since hydrogen has only one shell, two electrons make it stable as molecule. Thus hydrogen, in natural form exists as H2 instead of H.
Why does hydrogen gas exist as H2?
When two hydrogen atoms come together, it results in formation of a hydrogen molecule with two electrons in the outermost shell. Since hydrogen has only one shell, two electrons make it stable as molecule. Thus hydrogen, in natural form exists as H2 instead of H3.
Does hydrogen have to be H2?
Hydrogen, most abundant in the universe, is the chemical element with atomic number 1, and an atomic mass of 1.00794 amu, the lightest of all known elements. It exists as a diatomic gas (H2).
What happens when 2 hydrogen fuse?
Fusion reactions occur when two nuclei come together to form one atom. The reaction that happens in the sun fuses two Hydrogen atoms together to produce Helium. It looks like this in a very simplified way: H + H → He + ENERGY. That is called a mass deficit and that difference in mass is converted into energy.
Can H2 be aqueous?
In the aqueous fluids of the crust and upper mantle, H2 is ultimately present as a dissolved component.
Where is H2 used?
Nearly all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels.
Where does hydrogen fusion occur in the Sun?
core
Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun, and the transformation results in a release of energy that keeps the sun hot.
Why is it so hard to get atoms to fuse?
Since the nucleus of each atom is positively charged, there is a natural force that repels the atoms and keeps them from getting close enough to “fuse.” The fusion process, therefore, must use extreme temperatures and pressures to overcome the forces that naturally want to repel the atoms, and instead push their nuclei …
Is H2 a gas or aqueous?
Hydrogen
Hydrogen is a colorless, odorless gas. It is easily ignited.
Is H2 molecular or ionic?
. It consists of two hydrogen nuclei (protons) sharing a single electron. It is the simplest molecular ion.
What happens when hydrogen fuses into helium?
But less than half of that, surprisingly, is the fusion of hydrogen into helium. If you start with a mass of hydrogen gas and bring it together under its own gravity, it will eventually contract once it radiates enough heat away.

What happens when two hydrogen atoms come together?
When two hydrogen atoms come together, it results in formation of a hydrogen molecule with two electrons in the outermost shell. Since hydrogen has only one shell, two electrons make it stable as molecule.
What is the valence of a H2 molecule?
H2 – molecule. Single hydrogen atom contains 1 electron which is free electron i.e valance 1 and anything that is valence 1 is highly unstable. They have two option either to give up free electron or take 1 electron from neighboring hydrogen atom to fill its orbital ( which is 2 in this case ) .
