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.

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

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.

During typical DVCS, a nucleon (proton and neutron collectively) interacts with an electron. This reaction transfers some of ...

Each particle has its own charge and its own mass. The mass of an electron is very small compared to a proton or a neutron. 1 840 electrons have the same mass as 1 proton or neutron. Since the ...

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 ...

Having demonstrated this effect using proton-based FLASH treatments, researchers from Aarhus University in Denmark have now repeated their investigations using electron-based FLASH (eFLASH). Reporting ...
