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.

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 ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an atom The mass of electrons is very small compared to protons and neutrons. Since a ...

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.

Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions ... When the physicists compared the HERA data with the entropy ...
