Step 1: Recall the general rules for drawing Lewis structures.
- Determine the total number of valence electrons in the molecule. For a neutral fluorine atom, there are 7 valence electrons. - Place the atoms in a way that satisfies their octet rule, i.e., each atom should have 8 electrons in its outermost shell (except hydrogen, which needs only 2). - Distribute the remaining valence electrons as lone pairs on the atoms.
Step 2: Draw the initial Lewis structure for fluorine.
Since there is only one fluorine atom, we will place it in the center and surround it with its 7 valence electrons.
Final Answer
The correct Lewis structure for fluorine is: \chemfig{F} with the fluorine atom surrounded by a single line and three pairs of dots, representing its 7 valence electrons.
