Ions sodium

WebIons are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. WebSodium exists almost exclusively in the +1 oxidation state. The colorless sodium ion is Na+. Physical properties of Sodium. Sodium is so soft, that you can cut it with a knife.
