The formula H₂O shows that water is made from two atoms of hydrogen (H) bonded to one atom of oxygen (O). Katie: Time for some science. And today it's a chemistry classic, the periodic table.

where a catalyst creates oxygen ions. The arriving hydrogen protons and electrons bond with these oxygen ions, creating the two "waste products" of the reaction—water vapor and heat. Some of the ...

Hydrogen is the most abundant element in the universe, making up about 75% of the mass of the universe. It rarely exists as a gas on Earth; rather, it is usually present in a compound bonded to other ...

The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

Researchers have created an artificial gill that extracts oxygen from seawater to fuel cells, enabling robotic sea gliders or ...

These distinct patterns reveal how a particular molecule moves along H-bonds — allowing researchers to directly measure ...

Some people claim it can even cure cancer. The claim is based on an old theory that low oxygen levels can cause cancer. Hydrogen peroxide is an oxygenating compound, which means it’s a chemical ...

There are methods to generate hydrogen more efficiently, though, in a clean and sustainable process. that also produces useful heat and oxygen as byproducts. The key to the process? Concentrated ...

Oxygen can destroy hydrogen-producing enzymes. Researchers from Bochum and Osaka have discovered how an extraordinary protein survives in the presence of oxygen. Three years ago, a partial ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...
