Question

(a) The energy of the $2s$ state of lithium is -5.391 eV. Calculate the value of $Z_{eff}$ for this state. (b) The energy of the $4s$ state of potassium is -4.339 eV. Calculate the value of $Z_{eff}$ for this state. (c) Compare $Z_{eff}$ for the $2s$ state of lithium, the $3s$ state of sodium (see Example 41.9), and the $4s$ state of potassium. What trend do you see? How can you explain this trend?
