Web2 days ago · As per the Bohr model, the sodium atom consists of 11 protons, 11 electrons, and 12 neutrons. The protons and neutrons are present inside the nucleus of the atom due to which it acquires a positive charge. The electrons are said to revolve in a definite path around the nucleus. These circular paths are known as orbits or shells.
