So... for the element of SODIUM, you already know that the atomic number tells you the number of electrons. He who owns the information, owns the world – said V.Cherchill. temperatures on Earth increased? Sodium, like all the group 1 alkali metals, has one valence electron. Choose the calculator you like. The remaining "ions" also have twice the charge and so there will be more attraction between "ions" and "sea". In order to fill its valence shell, sodium has … 8 years ago. Sodium has a mass number of 23 and a stable sodium atom atom has 11 protons, 11 electrons, and 12 neutrons.
