2 SRA students are writing a report on the properties of fluorine. They decide to include a brief section about other elements that transition like fluorine. In order to find these elements, they look up where fluorine is located on the Periodic Table of elements shown above. Which of the following sets of elements should be included?

Nitrogen, oxygen, and neon, because they are in the same period as fluorine.

Helium, sulfur, and argon, because they are diagonal from fluorine.

Oxygen, neon, and chlorine, because they are connected to fluorine.

Chlorine, bromine, and iodine, because they are in the same group as fluorine.
