a.Find the electron configuration of iodine
b.How many unpaired electrons does iodine have?
3.Thought Questions:
a.In your own words describe how to write an electron configuration and why it is an important skill in the study of chemistry.
b.Describe the major concepts (Hunds, Pauli...etc.) and explain why each is a key part of the "tool kit" when describing electron configurations
c.Why is it possible to abbreviate electron configurations with a noble gas in the noble gas notation?
