However an element's mass numbers can vary ... 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.

Atoms are very small. 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 ...

Researchers from Kyushu University, Japan have revealed how a special type of force within an atom's nucleus, known as the ...

As they studied atomic disintegration, they kept seeing that the atomic number (number of protons in the nucleus, equivalent to the positive charge of the atom) was less than the atomic mass ...

This atomic nucleus, antihyperhelium-4 ... a key particle for understanding the mass of other particles. Collisions at the LHC recreate a state of matter called quark-gluon plasma, similar ...

The ALICE collaboration detected antihyperhelium-4 by analyzing data from lead nucleus collisions dating back to 2018. This detection was made possible thanks to a machine learning technique that ...
