In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

The proton gradients that power respiration are ... The whole pathway is pure chemistry, involving the reaction of one molecule with another, and therefore obeys the laws of stoichiometry; that ...

The formation of stars and cosmic chemistry are processes that are still largely unknown. A team of researchers recently discovered new sources of production for the H₃⁺ molecule, which ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

comparing the roaming mechanism followed by proton abstraction by H 2 to the traditional image of a doubly ionized molecule blowing apart due to repulsion of two positive charges—a process ...

“We have developed a novel, high-capacity small-molecule material for proton storage,” says Prof. Zhao. “Using this material, we successfully built an all-organic proton battery that is ...
