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 seven electrons in the second energy level.
Fluorine has an atomic number of 9, which means it has 9 electrons. The electron configuration is 1s² 2s² 2p⁵, where:
- The first energy level (n=1) contains 2 electrons (1s²).
- The second energy level (n=2) contains 7 electrons (2s² 2p⁵).
