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 ion has two positive protons but one electron so it is a positive ion. Helium ion, two neutrons, two protons and three electrons. Nuclear fission close nuclear fissionThe splitting of a large ...

He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of these ideas. Chadwick kept the problem in the back of his mind while working on other things.

Neutrinos are the most common particles in the universe. Not having an electric charge and being very light, they can move to ...

In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped ... nucleon by shooting a high-energy electron at it and watching how ...

Neutrinos are one of the most enigmatic fundamental particles. The Standard Model of particle physics suggests that these ...

Researchers from the KATRIN (Karlsruhe Tritium Neutrino) experiment report the most precise measurement of the upper mass limit of the neutrino to ...

In this environment, Mumpower’s team suggest that energetic photons in a jet collide with protons to create a neutron and a pion. Since these neutrons are have no electrical charge, many of them could ...
