The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element's atomic number, which is also 11. The number of neutrons can be found by subtracting the atomic number from sodium's atomic mass of 23. Sodium is an alkali metal, and it is from Group 1 on the periodic table and it is a metal. Sodium is Na.
