Question

Quizplus · Accepted Answer

The format for writing isotopes includes the element symbol followed by the sum of the number of protons and neutrons, written as a superscript before the atomic symbol. This isotope has 16 protons and 17 neutrons, so the atomic symbol is for sulfur (S) followed by a superscript of 33. The number of electrons is equal to the number of protons, so there are 16 electrons. The code after the isotope notation is not related to the information given and can be ignored. Choice B gives the correct elements and notation.
