18 protons and 20 neutrons
None. Protons and electrons are not constituents of a neutron. Both neutrons and protons are constituents of an atom's nucleus (core), while the electrons are situated in the electronic cloud around the nucleus.
The natural isotope 4He has 2 protons and 2 neutrons. The natural isotope 3He has 2 protons and 1 neutron.
When a neutron star is formed, protons and electrons are crushed, they collide and become neutrons.

1 proton,1electron and no neutron
Carbon does not have an atomic number of 14.
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
hey perhaps your question is incomplete. but if your question is what is protons and neutron relationship then a neutron plus a positive charge having mass equal to electron mass then proton forms.
