Which statement best describes the arrangement of electrons in an atom of fluorine (F)?

The arrangement of electrons in an atom of fluorine (F) is that it has two electrons occupying the first energy level and seven electrons occupying the second energy level.

In an atom of fluorine (F), the electrons are arranged in shells or energy levels around the nucleus. The electron configuration of fluorine is 1s2 2s2 2p5, indicating that it has a total of 9 electrons. These electrons are distributed in the first energy level (K shell) with 2 electrons, and the second energy level (L shell) with 7 electrons. So, in summary, the electrons in an atom of fluorine are arranged in two energy levels, with 2 electrons in the first level and 7 electrons in the second level.
