Which species have the same number of electrons?I. S2–II. Cl–III. NeA.I and II onlyB. I and III onlyC. II and III onlyD. I, II and III
Question
Solution 1
To answer this question, we need to know the atomic number of each species, which represents the number of protons and, in a neutral atom, also the number of electrons.
I. S2–: Sulfur (S) has an atomic number of 16, so a neutral S atom would have 16 electrons. However, S2– indicates that this ion Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
