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.

Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

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 ...

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 ...

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

Having a “magic” number of protons or neutrons means there are enough to fully occupy the nuclear valence shells (outermost orbits around the nucleus) in an atom and give it stability.

Scientists have achieved an incredible feat—mapping the forces inside a proton with extreme precision, uncovering the immense forces that hold quarks together. Using lattice quantum chromodynamics, ...

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 ...

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

Atomic nuclei with “magic numbers” of protons or neutrons in their nuclear shells are extremely stable. Nuclear physicists are especially interested in nuclei with doubly magic numbers—those that have ...
