Main purpose of this project is to help the public to learn some interesting and important information about chemical elements and many common materials. Atomic weight of Sodium is 22.98976928 u or g/mol. Sodium (symbol Na, from the Latin name natrium) is the chemical element number 11 in the periodic table of elements. Atomic number and mass number are always whole numbers because they are obtained by counting whole objects (protons, neutrons, and electrons). Sodium is a reactive element, especially with water and other chemical compounds, that is why it can not be found in nature as metal. Therefore, the number of electrons in neutral atom of Sodium is 11. For example, the atomic number of sodium is 11. Since, in a neutral molecule, the number of protons is equal to the number of electrons, we can also deduce that sodium also has eleven electrons. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
