Why h2

Because there are two hydrogen atoms, we call this diatomic hydrogen, di meaning two. Because the hydrogen atoms are covalently bonded together they form a molecule; so H2 is also referred to as molecular hydrogen. We can also refer to it as dihydrogen. The hydrogen molecule contains two protons and two electrons making it a neutrally-charged molecule. It is a colorless, odorless, tasteless, non-metallic highly flammable gas, and very explosive above a 4.

Energy Department-funded analysis has shown that hydrogen and fuel cells have the potential to achieve the following reductions in emissions:. Transit buses: demonstrated fuel economies of approximately 1. The greatest challenge for hydrogen production, particularly from renewable resources, is providing hydrogen at lower cost. For transportation fuel cells, hydrogen must be cost-competitive with conventional fuels and technologies on a per-mile basis.

To reduce overall hydrogen cost, research is focused on improving the efficiency and lifetime of hydrogen production technologies as well as reducing the cost of capital equipment, operations, and maintenance. Sources of Energy. Production Pathways. Energy Carrier. Uses for Hydrogen.

Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical. H2 is the smallest molecule in the universe. That means it can go where nothing else can …including into your mitochondria which are the powerhouses of your cells. Hydrogen gas cannot be kept in plastic because it will pass right through the walls of the container. When the Hydrogen atom loses an electron all that is left is a proton.

This is the form of Hydrogen that produces the ATP enzyme that powers our cells and mitochondria. Hydride is a hydrogen atom which has an extra electron. This means that it is a negatively charged ion , or anion. That is why Hydride ion H- has the minus sign distinguishing it from a regular Hydrogen atom H. The two dots after the H means that this ion has two electrons instead of just one. The extra electron means that H- is not a free radical however it is not stable because this form of hydrogen is a very strong base extremely alkaline which reacts with water to produce hydroxide OH — and molecular hydrogen H 2.

Hydride H: — also reacts with metals to form chemical compounds which are reducing agents. Hydroxide OH— is also known as the hydroxyl ion. This reaction is reversible. The Hydroxide ion OH — is a base alkaline.

The Hydroxide ion is not a free radical or an antioxidant.
