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 ...

He based his calculations on the hydrogen atom, and more specifically, on the time it takes for the spin of a hydrogen atom’s electron to change relative to its proton. It’s known as the ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...

“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 ...
