Problem 38E

List these types of electromagnetic radiation in order of (i) increasing frequency and (ii) decreasing energy per photon:

a.        gamma rays

b.        radio waves

c.        microwaves

d.        visible light

Step-by-Step Solution:
Step 2 of 3

Solution Step1 First ionization energy is the energy required to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. For Pb(Atomic number= 82) having electronic configuration [Xe]4f 5d 6s 6p it is the energy 14 10 2 2, required to remove the outermost 6p electron.The equation can be written as Pb (g)-----------> Pb +(g)e - ------> I 1 Step 2 The second ionization energy is the amount of energy needed to remove the second outermost electron.Second ionization energy will be greater than first ionization energy.This is because once you have removed the first electron you are left with a positive ion. Trying to remove a negative electron from a positive ion is going to be more difficult than removing it from an atom.For Pb equation for second ionization energy is Pb +(g)-------------> Pb 2+(g) e- ------> I 2
