What is the atomic number of hydrogen 2?
The atomic number of hydrogen-2 is one. This is because the number of protons remains the same in all isotopes of an element.
Does H2 exist?
H2 is a gas which forms when two hydrogen atoms bond together and become a hydrogen molecule. H2 is also called molecular hydrogen.It consists of two protons and two electrons. Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical.
