Identify the atomic number of argon from the periodic table. The atomic number represents the number of protons in the nucleus of an atom.
Recall that a neutral atom has an equal number of protons and electrons to balance the charge.
Since argon is neutral, the number of electrons equals its atomic number.
Write the relationship: Number of electrons = Atomic number of argon.
Use the atomic number of argon (which is 18) to determine the number of electrons in a single neutral argon atom.
