* Energy Levels: The first two energy levels are filled, meaning they have a total of 2 + 8 = 10 electrons.

* Third Level: The third energy level has 6 electrons.

* Total Electrons: This gives us a total of 10 + 6 = 16 electrons.

* Neutral Atom: Since it's neutral, the number of electrons equals the number of protons.

* Atomic Number: The number of protons is the atomic number.

Therefore, the element is sulfur (S), which has an atomic number of 16.
