Step 1: Understand the problem
The problem asks for the number of valence electrons in an atom of the element fluorine. Valence electrons are the outermost electrons in an atom and are involved in the formation of chemical bonds.
Step 2: Know the properties of fluorine
Fluorine is a chemical element with the atomic number 9, which means it has nine protons in its nucleus. As a result, a neutral fluorine atom also has nine electrons.
Final Answer
Seven. Although the answer might seem counterintuitive because seven is not mentioned in the options, it's important to remember that the question asks for the number of valence electrons in a fluorine atom, which is indeed seven.
