Quizplus · Accepted Answer

Y has 18 protons and Z has 20 protons, indicating that they are two different elements. The fact that they have different numbers of electrons (Y has 10 and Z has 18) suggests that they are not isotopes of the same element. They also do not have a net positive or negative charge, so they are not cations or anions.
