Problem
A PES spectrum for a second-period element displays two prominent peaks: one at 25 eV with a relative height of 2 and another at 15 eV with a relative height of 6. Describe what the 3 : 1 ratio of these peak heights indicates about the number of electrons in the two corresponding subshells.
