Question

how does the oxygen spectrum compare to the hydrogen and helium spectrum?

Answer 1

In hydrogen and helium spectrum, we have energy levels = - 13.6/n^2.

And depending upon the orbit no "n" we can find energies of different levels.

The exact formula for energy is - 13.6z^2/n^2

Here z is atomic number.

In case of oxygen we will put z=8 and the remaining equations will be same as hydrogen and helium atom depending upon orbits.

Let us try to find the differences.

If n=1

E for hydrogen =-13. 6

E for oxygen =-13. 6*64

For n =2

E for hydrogen =-13. 6/4

E for oxygen=-13. 6*64/4
