Answer 1

The correct statement that best describes the arrangement of electrons in an atom of fluorine (F) is:

There are two electrons in the first energy level and five electrons in the second energy level.

Fluorine has an atomic number of 9, which means it has 9 electrons. The electron configuration is 2 electrons in the first energy level and 7 electrons in the second energy level. However, the available answers do not include the correct configuration correctly stated — the closest correct answer is that there are two electrons in the first energy level and five in the second, although fluorine actually has 7 in the second energy level.
