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 relative charge of a nucleus is the same as its proton (atomic) number ... two positive protons but one electron so it is a positive ion. Helium ion, two neutrons, two protons and three ...

But in the early 1930s, scientists discovered that some atomic nuclei ... They are the same for both protons and neutrons.

“According to our model, the decay probability of a neutron strongly depends on its state. Logically, this also results in ...

The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it ...

The atomic nucleus is made up of protons and neutrons, particles that exist through ... of a specific particle being created in an electron or proton collision with the nucleus.

For many years, scientists believed that fundamental particles like protons and neutrons that form an atomic nucleus ...

Hybrid model A new description of nuclei combines the quark–gluon model of particle physics with the proton–neutron ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons ... in an electron or proton ...
