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. Since atoms are electrically neutral, there must also be nine electrons in a neutral fluorine atom.

Final Answer

A neutral fluorine atom has five valence electrons.
