Answer:
b. 16 protons, 18 neutrons, and 18 electrons
Explanation:
Things to be remembered
Negative charge on any ionic species indicates gained the electrons
Positive charge on any ionic species indicates lost the electrons
A sulfur atom has 16 protons, 18 neutrons, and 16 electrons, A sulfide ion has a 2– charge which indicates that sulphur has gained two electron from any other atom, ion or species!

<h3>What is atomic theory?</h3>
Atomic theory is the scientific theory that matter is composed of particles called atoms.
The discoveries of subatomic particles such as;
- electron by J.J. Thomson
- proton by Ernest Rutherford
- neutron by James Chadwick
- nucleus by Ernest Rutherford
all contributed in the development of the atomic theory.
From the information given in the passage J.J. Thomson experiment gave rise to atomic model while Rutherford, Geiger and Ernest Marsden, performed the experiment that discovered nucleus and proton.
Thus, characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.
