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.

A kind of umbilical cord between different quantum states can be found in some materials. Researchers at TU Wien have now ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

The relative mass of a nucleus is the number of protons and neutrons ... A helium atom that has lost or gained an electron is an ion. The ion has two positive protons but one electron so it ...

For example, the electron in a hydrogen atom attracts the proton that is the nucleus, so the effective distance between them changes. QED has a prescription to calculate the self-energy ...

thin compartments of the endoplasmic reticulum or the compacted chromatin within the nucleus. An electron micrograph therefore provides an excellent blueprint of a cell's inner structures.

This article was originally published with the title “ What Holds the Nucleus Together? ” in Scientific American Magazine Vol. 189 No. 3 (September 1953), p. 58 doi:10.1038 ...

the researchers identified candidates for excitations in this particular nucleus. "All three types of experiments (i.e., photon, electron and proton scattering) are sensitive to dipole excitations and ...

It turns out that in order to answer that question, you need a little of quantum mechanics and a sprinkling of Einstein's ...

An unstable nucleus can emit a fast-moving electron called a beta (β) particle, to become more stable. Beta radiation is made up of a stream of beta particles emitted from unstable nuclei.
