Boron is the fifth element in the periodic table. For the first ionization of boron, the ionization energy is 0.8006 MJ/mol. Calculate the effective nuclear charge (Zeff) for the first ionization of boron.

Expert Solution

Effective nuclear charge (Zeff) = sq.rt.(E.n^2/Rh)

Rh = 2.178 x 10^-21 kJ

E = 0.8006 MJ/mol = 800.6 kJ/mol

n = 2

we get Zeff for boron,

Zeff = sq.rt.(800.6 x 2^2/2.178 x 10^-21) = 1.21 x 10^12 mol-1

Explain how the successive (first, second, third, etc) ionization potentials change in each atom.3. For most atoms, there are one or two huge jumps in the ionization potential. Explain why these occur. In aluminum, explain these huge increases using the valence electrons.4. Explain any trend you observe when looking at only the first ionization energies of each of the 13 elements.
