Just about everyone knows that water is H2O, meaning two hydrogen atoms and one oxygen atom. What might surprise people is that scientists have never before been able to actually watch hydrogen ...

The number of protons is what defines the element. Oxygen, for example, has eight protons. However, the number of neutrons in an atom can vary, leading to different forms of elements, called isotopes.

Real atoms are extremely small and Linus could not possibly see them. The colored spheres in the game represent a large supply of that atom. For example, the red sphere for oxygen could represent a ...

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 ...

When two hydrogen atoms and an oxygen atom get close enough, the electron from each atom feels an attraction from the protons in the other atom's nucleus. This attraction pulls the atoms together. The ...
