Here's how to determine the number of electrons and neutrons in a sulfur atom:

* Atomic Number: Sulfur's atomic number is 16. This means it has 16 protons in its nucleus.

* Electrons: In a neutral atom, the number of protons and electrons is equal. Therefore, a sulfur atom has 16 electrons.

* Neutrons: To find the number of neutrons, you need the atomic mass. Sulfur's atomic mass is approximately 32.

* Neutrons = Atomic Mass - Atomic Number

* Neutrons = 32 - 16 = 16 neutrons

So, a sulfur atom has 16 electrons and 16 neutrons.
