Hydrogen has one electron, which leaves it with a partially full shell. To have a full shell it must have two electrons. As a result, one hydrogen atom will form a covalent bond with another, ad the two atoms share their electrons.

What is the subscrift of hydrogen?
2: As a gas the molecules of hydrogen have the formula H2.
Is H2 hydrogen?
"H" is the chemical symbol for Hydrogen. "H2" is the symbol for a molecule that contains two atoms of hydrogen. Under normal conditions in the Earth's atmosphere, hydrogen gas is usually found in the form of molecules consisting of two atoms.
What elements are H2?
H2 Is a diatomic hydrogen molecule. It is made up of two hydrogen molecules that are joined together.
Why does hydrogen molecule does not exist?
Hydrogen molecules do exist (as H2); this is how hydrogen is found in nature.
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
What does Hydrogen combine with to make water?
Hydrogen combines with oxygen to form water. The reaction is two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2) to form two molecules of water (H2O).
What is H2S?
H2S stands for Hydrogen Sulphide.It is a gas.
What are two molecules of hydrogen represented by?
Two molecules of hydrogen arte represented by '2H2'. This means H2 & H2 . 'H2' is ONE molecule of hydrogen . It consists of two(2) atoms of hydrogen . It can be represented by 'H-H'. NB With the exception of the Noble Gases , all other gas molecules contain at least two atoms.
What is the balanced Equation showing the reaction of carbon and hydrogen to form methane?
The molecular formula for Methane is CH4 It's 1 atom carbon, 2 hydrogen molecules (Hydrogen molecules come in H2 gases) so the formula would be C + 2(H2) = CH4

Is h a molecular element?
Hydrogen, in its elemental form, forms diatomic molecules, H2 , so it can be considered molecular.
Why does H2 molecules exist when He2 does not?
H2 technically does contain molecules. Or at least, molecule. H2 is two hydrogens covalently bonded, so that the lowest energy level is filled. Since H2 has two atoms (hydrogen and hydrogen), it is not an element, because there is more than one atom. H2 is a molecule itself. However, in context of nature, it is rare that you would ever find an H2 molecule on its own unless you were working with one in a laboratory. So, if you were considering the whole of an H2 gas, there would be many molecules of H2. Short answer: H2 is a molecule itself. Many H2 means there are many molecules of H2.
What do you mean by 3 H2?
It might refer to 3 molecules of H2 (diatomic hydrogen).
Which element is h2?
H2 is the elemental form of hydrogen.
