Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner structure to improve calculations of a phenomenon in atomic physics known as the ...

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 ...

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 ...

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 molecule of ammonia has 1 nitrogen atom and 3 hydrogen atoms. Ask students to use Snap Cubes to make an ammonia molecule. Then show students the animated Snap Cube model of an ammonia ...

In one molecule of water, there are two hydrogen atoms and one oxygen atom. Particle diagrams can also show the ratio of atoms of each element in a compound which in turn can tell us the formula o ...
