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 ...

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 ...

How can we produce clean hydrogen without burning fossil hydrocarbons or other non-renewable energy sources? We can do so through photoelectrochemistry, or artificial photosynthesis, a method ...

The goal of this activity is to construct a carbon atom. You'll start with a hydrogen atom, which contains one proton and one electron. To build other atoms, just add protons, neutrons ...

As the wonderfully named [ArtichokeHeartAttack] explains in the remarkably thorough project documentation, the characteristic 1420.4-MHz signal emitted when the spins of a hydrogen atom’s proton ...

The typical size of atoms and small molecules is around 1 × 10-10 m (0.1 nm). For example: diameter of a hydrogen atom, H 1.0 × 10-10 m width of a hydrogen molecule, H 2 2.9 × 10-10 m ...

Explain that a water molecule has two hydrogen atoms and one oxygen atom. Ask students to use Snap Cubes to make a water molecule. Then show students the animated Snap Cube model of a water molecule.
