Answer 1

The correct isotope notation for the given ion is 32S-2.

Step-by-step explanation:

The correct isotope notation for an ion with 16 protons, 17 neutrons, and 18 electrons is D) 32S-2. The element with 16 protons is sulfur (S), and since the ion has 2 more electrons than protons, it has a charge of -2. The mass number is calculated by adding the number of protons and neutrons, which in this case is 16 + 17 = 33.
