Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal ...

The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...

For example, the electron in a hydrogen atom attracts the proton that is the ... as it could point the way to physics beyond the standard model. More information: V. A. Yerokhin et al, Two-Loop ...

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 ...
