The correct answer is that 4 neutrons, 29 electrons, and 29 protons make up copper-63.
The nucleus, which is located in the middle of the atom, contains protons and neutrons. The nucleus is far smaller than the entire atom. Around the nucleus, the electrons are organised in shells. A core nucleus that is often surrounded by one or more electrons makes up an atom. The charge of every electron is negative. The positively charged nucleus has one or more protons and neutrons, which are relatively heavy particles. Protons and neutrons roughly share the same mass, however, the mass of an electron is quite small. Unlike the neutron, which has a negative charge, a proton.
