What could be the spectral lines (energy level diagram ) for Aluminium ?

Answer 1

Hi Vaishali J.,

So draw the ground-state electron configuration for Aluminum (as an atom, we presume?). Then pump one electron from the highest occupied ground state to various higher states (shells + subshells). Each of these have energies, and you should be able to relatively rank them in energy, even if you don't know them in detail! -- based on the order that atoms in the periodic table populate their shells. Then when the electron drops back, it has emission lines corresponding to the energy difference(s). A piece of cake -- not that it's easy, rather that aluminum salts are present in the "double-acting" baking powder you might use to bake a cake.
