5) The diagram below shows a plausible series of atomic radii for a column of the
periodic table. Given the concepts of atomic orbitals and multi-electron interactions
we have discussed, answer the following questions. (You need only the qualitative
radii information given).
Will the general trend for each property below be to INCREASE or DECREASE?
Choose and briefly justify your answer.
Example: The energy to remove one electron from an
atom.
Atomic Radius
Answer: Energy will DECREASE because the valence
electrons will be more shielded, and thus
experience a lower Zeff.

a) The average radial distance of an electron
a ls orbital.
