Protons and neutrons are part of the nucleus of an atom
These particles are: protons, neutrons and electrons.
Protons and Neutrons compose the nucleus of an atom. Protons and nutrons weight combine to give the mass of the atom. In most atoms, the amount of Neutrons is equivalent to the amount of Protons.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
protons and neutrons are about 1 amu
Quarks
An atomic nucleus consists of protons and neutrons.
The atomic nucleus contain protons and neutrons; protons and neutrons are formed from quarks and gluons.
There are two types of subatomic particles hypothesized to comprise protons and neutrons. Elementary particles having mass by the types of quarks, leptons and bosons are the first. The second are composite particles, which include baryons, mesons, and leptons.
Protons and neutrons have the mass of 1 amu.
protons and neutrons. both are present in the nucleus.
For example protons and neutrons are formed from quarks and gluons.
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
