* Protons: The number of protons defines the element. Sulfur's atomic number is 16, meaning it always has 16 protons.
* Neutrons: The mass number (36 in this case) represents the total number of protons and neutrons. To find the number of neutrons, subtract the number of protons from the mass number: 36 - 16 = 20 neutrons.
Therefore, sulfur-36 has 16 protons and 20 neutrons.
