Final answer:
A neutral sulfur atom has 16 protons, 16 electrons, 6 valence electrons, and a charge of 0.
Step-by-step explanation:
The number of protons in a neutral sulfur atom is 16. This is because the atomic number of sulfur is 16, and the atomic number represents the number of protons in an atom.
The number of electrons in a neutral sulfur atom is also 16. In a neutral atom, the number of electrons is equal to the number of protons.
The valence electrons in a neutral sulfur atom are the electrons in the outermost shell. Sulfur is in Group 16 of the periodic table, so it has 6 valence electrons.
A neutral sulfur atom has a charge of 0. Since the number of protons and electrons is equal, the positive charges from the protons balance out the negative charges from the electrons.
