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 total number of particles in the nucleus, (i.e. the sum of all the protons and neutrons), is called the mass number A. A is the mass number (the sum of the protons and neutrons) Z is the ...

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.

According to a study published in Nature Physics, a TU Darmstadt-led research team at the GSI Helmholtz Centre for Heavy Ion ...
