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, meaning it has 9 electrons. These electrons are arranged as follows: 2 electrons in the first energy level (1s orbital) and 7 electrons in the second energy level (2s and 2p orbitals).
