3. Atomic physics of sodium. In the sodium atom, there is a transition between the 3s and 3p atomic states that produces the yellow-orange light seen in many street lamps a. Sodium has 11 protons and 11 electrons with ten of the electrons filling the n =1 and n = 2 levels. Including interactions between the outer electron and the electrons in the underlying shells, should the 3s or the 3p energy level have the highest energy? Use properties of...

answer a b or c
Why is the atomic radius of magnesium ion much smaller than that of a neutral charged magnesium atom? (See the atomic radius graph) The magnesium ion's electrons require less space. No electrons are lost, they move to unoccupied spaces about the nucleus. The magnesium ion has fewer principle quantum energy levels, this causes a decrease in atomic radius. The magnesium ion has a higher Z-effective nuclear charge. The magnesium ion has more principle quantum energy...
