However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also ...

Since a nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus.

An experiment more than 10 years in the making has delivered its first glimpse of the hurricane of particles whirring inside subatomic particles called neutrons ... of an atom is a beehive ...

neutrons, the electrically neutral particles that sit alongside positively charged protons in the nucleus of an atom, can be used to probe the nature and structure of materials, just as X-rays ...

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 building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

By interacting with nucleons, these particles could alter the structure of neutron stars, which could in turn impact their cooling. Building on this idea, researchers at the University of Alicante ...

"Unlike previous bounds based on axion emission and energy loss, our approach is based on how the QCD axion field alters the neutron star's structure, compressing its envelope and accelerating ...
