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.

In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus ... He called it a neutron, and imagined it as a paired proton and electron.

When a carbon-14 atom decays, one of its eight neutrons turns into a proton, emitting an electron (with a charge of -1) in the process. The atom is now stable. And with seven protons and seven ...

A helium atom that has lost or gained an electron is an ion. The ion has two positive protons but one electron so it is a positive ion. Helium ion, two neutrons, two protons and three electrons.

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

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 ...

For the first time, scientists have successfully mapped the shape of an electron while ... stay attached to an atom. Inside ...

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 ...

neutrons and electrons. For example, a hydrogen atom has one proton, one electron and zero neutrons, while uranium has 92 ...
