The sodium Bohr model, developed by Niels Bohr, represents the electronic structure of the sodium atom. It postulates that electrons orbit the nucleus in quantized energy levels, with each energy level corresponding to a specific radius. In the sodium model, the single outermost electron occupies the third energy level (n=3), with its three subshells (s, p, d) further divided into sub-subshells (ms, ml, and mj) determined by the electron’s angular momentum and spin. This arrangement influences the atom’s chemical reactivity, as the outermost electron is loosely bound and easily lost, resulting in sodium’s characteristic monovalent behavior.
