Helium. If there are no electrons, it is an alpha particle (typically created in nuclear reactions)
Alpha radiation.
That's a description of an alpha particle. That "bundle" of two protons and two neutrons is actually a helium-4 nucleus. Use the link below to learn more.
its called protons and neutrons
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
alpha particle
Nucleus (and it consists of protons and neutrons).
The two types of particles in the nucleus are called protons and neutrons.
it is similar to an alpha particle
The neutral particles found in the nucleus on an atom are called neutrons. Positive particles found in the nucleus are protons.
The two particles in a nucleus are protons and neutrons. Protons carry a positive charge, while neutrons have no charge. Together, they make up the majority of an atom's mass and are responsible for holding the nucleus together through strong nuclear forces.
The elementary particles that make up protons and neutrons are called quarks. Protons are composed of two up quarks and one down quark, while neutrons consist of one up quark and two down quarks. Both protons and neutrons are classified as baryons, which are a type of hadron. Quarks are held together by the strong force, mediated by particles called gluons.
Protons and neutrons; these particles contain quarks and gluons.
