Question

Quizplus · Accepted Answer

- P^-3 corresponds to the electron configuration of chlorine (Cl). - The atomic number of Cl is 17, meaning it has 17 protons in its nucleus. - The symbol for Cl in the periodic table lists the atomic mass as 35.45, which is the weighted average of the masses of all Cl isotopes found in nature. - To find the number of neutrons, we subtract the atomic number (protons) from the atomic mass (protons + neutrons): neutrons = 35.45 - 17 = 18.45 ≈ 18 - Therefore, the correct answer is E, 16 neutrons.
