🤓 Based on our data, we think this question is relevant for Professor Mamiya's class at TXSTATE.
Rank the following elements by effective nuclear charge, Z eff, for a valence electron from highest to lowest Zeff:
Po, Rn, Ba, Bi, Pb (same as ionization energy)
We’re being asked to rank the given elements in order of decreasing effective nuclear charge (Zeff) of their valence electron.
Recall that the effective nuclear charge is the force exerted by the nucleus onto an electron. The Zeff can be calculated using Slater’s Rules.
