c. You can imagine that electrons on the outer orbitals will experience less attraction from the nucleus due to the repulsion from electrons on the inner orbitals. This is called the shielding effect. The charge an outer electron felt is called the effective nuclear charge. Please use Slater's rule to determine the effective nuclear charge for one 3d electron and one 4s electron. d. From its electron configuration, you notice that there are 8 electrons on 3d orbitals for the nickel atom. Some electrons are paired but some are not. There will be paring energy (π) and exchange energy (T₂). How many π and π are there for 8 electrons in the 3d orbitals?

The first ionization energy of helium is 2370kJmol1 , the highest for any element. (a) Define ionization energy and discuss why for helium it should be so high. (b) Which element would you expect to have the highest second ionization energy? Why? (c) Suppose that you wished to ionize some helium by shining electromagnetic radiation on it. What is the maximum wavelength you could use?
The outermost electron in an alkali-metal atom is sometimes described as resembling an electron in the corresponding state of a one-electron atom. Compare the first ionization energy of lithium with the binding energy of a 2s electron in a one-electron atom that has nuclear charge Zeff , and determine the value of Zeff that is necessary for the two energies to agree. Repeat the calculation for the 3s electron of sodium and the 4s electron of potassium.
The work function is the energy required to remove an electron from an atom on the surface of a metal. How does this definition differ from that for ionization energy?
Until recently, it was thought that Ca was unstable, and that the Ca atom therefore had a negative electron affinity. Some new experiments have now measured an electron affinity of +2.0kJmol1 for calcium. What is the longest wavelength of light that could remove an electron from Ca ? In which region of the electromagnetic spectrum does this light fall?
Answer the following questions, assuming that ms, could have three values rather than two and that the rules for n, l, and ml are the normal ones. a. How many electrons would an orbital be able to hold? b. How many elements would the first and second periods in the periodic table contain? c. How many elements would be contained in the first transition metal series? d. How many electrons would the set of 4f orbitals be able to bold?
The first ionization energies of As and Se are 0.947 and 0.941 MJ/mol, respectively. Rationalize these values in terms of electron configurations.
The energy needed to remove one electron from a gaseous potassium atom is only about two-thirds as much as that needed to remove one electron from a gaseous calcium atom, yet nearly three times as much energy as that needed to remove one electron from K+ as from Ca+ . What explanation can you give for this contrast? What do you expect to be the relation between the ionization energy of Ca+ and that of neutral K?
The following questions use concepts from this and previous chapters. Why is the radius of Li+ so much smaller than the radius of Li? Why is the radius of F so much larger than the radius of F?
