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.

They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us that chlorine has ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei – the center part of atoms, which make up all matter – were more ...

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 ...

In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus. But they and other researchers were finding that the proton did not seem to be the only ...

The AMoRE experimental collaboration in South Korea has reported not finding evidence of neutrinoless double beta decay after ...

In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as ...

Scientists have acquired direct evidence of rare, pulsing pear-shaped structures within atomic nuclei of the rare-earth element Gadolinium, thanks to new research.

This means the nuclear shells are filled, resulting in a more stable nucleus, doubly so in the case of doubly magic nuclei. The protons and neutrons are paired and symmetrically arranged ...
