41 orbital diagram of sodium
Na (Sodium) is an element with position number 11 in the periodic table. Located in the III period. Melting point: 97.8 ℃. Density: 0.97 g/cm 3 . Electronic configuration of the Sodium atom: 1s 2 2s 2 2p 6 3s 1. Reduced electronic configuration Na: [Ne] 3s 1. Below is the electronic diagram of the Sodium atom Distribution of electrons over ... Sodium Atomic Emission Spectrum The sodium spectrum is dominated by the bright doublet known as the Sodium D-lines at 588.9950 and 589.5924 nanometers. From the energy level diagram it can be seen that these lines are emitted in a transition from the 3p to the 3s levels. The line at 589.0 has twice the intensity of the line at 589.6 nm. Consider the diagram of Sodium below: Circled are orbitals both containing $2$ electrons each which combine using LCAO to give a set of bonding and antibonding electrons. However, the $4$ electrons involved in this bonding appear to only give $3$ electrons in the bonding and antibonding MO's produced...
