(1) Write the electron configuration for a S atom. Use the underline feature to underline the valence electrons.  (2) Using this configuration, indicate which energy level holds the valence electrons and how many valence electrons there are.  (3) How many bonds would S form when it participates in covalent bonding? (Think about the “rules” for why things bond and how many electrons elements “want”).

A Pt presents moderately short of breath. He states he had a cast put on his left leg seven days ago after surgery for a ruptured Achilles tendon. This morning, while he was watching television, he suddenly became short of breath. He has a history of asthma, for which he takes Xopenex as needed, and is taking Tylenol with codeine for pain related to his surgery. The patient’s lung sounds are clear and equal, SpO 2 is 90 percent on room air, heart rate is 100 and regular, respirations are 24 and slightly labored, blood pressure is 128/88, and the patient is afebrile. These findings are most consistent with:

The structure of the amino acid Tyrosine is below. Looking JUST at the “R” group highlighted in blue answer the following about Tyrosine.  The R group of Tyrosine has an OH group on it. The major IMF (intermolecular force) that this R group will participate in is [blank1] which means this amino acid is most likely to exist in a [blank2] part of a protein structure.
