Homework 10, due Sept 28

    Ionization Potential T₀ = E₀ / kᵦ. 

    kᵦ = 8.62×10⁻⁵ eV K⁻¹.

1) What is the ionization potential of H 0 in K?

    T₀ = 158000 K.

2) What are the ionization potentials, in K, of the all 14 atoms and ions of
Si? (Si 0 , Si + , Si 2+ , Si 3+ , Si 4+ , ... Si 13+ ?)
    
    T₀[Si I] = 9.46E+04 K. (M)
    T₀[Si II] = 1.90E+05 K. (M)
    T₀[Si III] = 3.89E+05 K. (M)
    T₀[Si IV] = 5.24E+05 K. (M)
    T₀[Si V] = 1.94E+06 K. (L)
    T₀[Si VI] = 2.38E+06K. (L)
    T₀[Si VII] = 2.86E+06 K. (L)
    T₀[Si IIX] = 3.52E+06 K. (L)
    T₀[Si IX] = 4.07E+06 K. (L)
    T₀[Si X] = 4.66E+06 K. (L)
    T₀[Si XI] = 5.53E+06 K. (L)
    T₀[Si XII] = 6.07E+06 K. (L)
    T₀[Si XIII] = 2.83E+07 K. (K)
    T₀[Si XIV] =  3.10E+07 K. (K)


3) On the table you make of ionization potentials, indicate whether the
outermost electrons are in the K, L, or M shell.

    Above.

4) Make a plot with the x axis the ion number (0 for Si 0 , 1 for Si + , etc), the y
axis the ionization potential in eV

a. First linear y axis

b. Second log y axis
