What is actually happening when someone takes a temperature?

A person has a fever if their body temperature rises above the normal range of 98–100°F (36–37°C). It is a common sign of an infection. As a person's body temperature increases, they may feel cold until it levels off and stops rising. People describe this as “chills.”

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

b is the correct answer
