Molecular hydrogen (H2) is a colorless, odorless, tasteless, and non-toxic gas that is the lightest of all gases. It is also the most abundant element in the universe. Molecular hydrogen consists of two atoms of hydrogen bonded together by a covalent bond. The bond between the two atoms is very strong, and it takes a lot of energy to break it.
Molecular hydrogen has many uses. It can be used as fuel for rockets and other vehicles, as well as for industrial processes such as welding and cutting metals. It can also be used to produce electricity, and it is an important component of some types of batteries. In addition, molecular hydrogen can be used to create water or other chemicals when combined with oxygen.
The properties of molecular hydrogen make it an ideal gas for many applications. For example, its low density makes it ideal for use in balloons and blimps. Its high boiling point makes it useful for pressurizing liquid nitrogen or other cryogenic fluids. And its lack of reactivity means that it can be used to store highly reactive materials such as uranium without danger of explosion or contamination.
