O ELECTRONIC STRUCTURE Interpreting the radial probability distribution of an orbital Here is a sketch of the radial probability distribution of three orbitals: 0.0020 0.0013 probability 0.0010- 0.0005 VAV 500 1000 0 1500 2000 2500 3000 distance from nucleus (pm) Use this sketch to answer the following questions. What is the most likely distance from the nucleus for an electron in orbital A? Note: your answer must be within 50 pm of the exact answer to be graded correct. pm List the orbitals in order of increasing energy: Suppose all three orbitals were inner orbitals of an atom. In which orbital would an electron be most effective at screening the charge of the nucleus from(choose one) the outer electrons? Explanation Check

Explanation / Answer

*one question at a time please

1. The highest peak (highest probability) of the curve for the A orbital is approximately at 1900 pm

2. C < B < A, C has the lowest energy

3. C, electrons in C are closer to the nucleus so this will be most efective at screening the charge
