Sodium typically has 12 neutrons in its most common isotope, sodium-23. When sodium loses an electron to form the Na+ ion, it still has the same number of neutrons due to the neutral nature of neutrons.
The ion Na+ has 11 protons, 12 neutrons, and 10 electrons. This is because sodium has an atomic number of 11, meaning it naturally has 11 protons and 11 electrons, but as an ion with a +1 charge, it has lost 1 electron.
