Ionization breaks the hydrogen atom down into its positive ions (hydrogen protons) and negative ions (electrons). Both types of ions are naturally drawn to the cathode situated on the other side ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

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 ...

This particle diagram shows a mixture made up of water and carbon dioxide. The water molecules each have two white hydrogen atoms and one red oxygen atom (H₂O). The carbon dioxide molecules each ...

Here, the oxygen atom is red, carbon is black and hydrogen is white. Image caption, A ball-and-stick model of methane Molecules can be drawn in different ways. In this diagram of methane (CH₄ ...

“And the problem with a hydrogen car, if something goes wrong, it’s like the atom bomb went off,” he said. “You’re not recognizable. They'll say, ‘We thought it was Marjorie Taylor ...
