Consider the transition metal complex Cr(H₂O)₆^3-.The total number of valence electrons this complex possesses is ____. A)2 B)8 C)10 D)12 E)18

Question

Quizplus · Accepted Answer

There are multiple atoms and ligands within this complex, which all contribute to the total number of valence electrons. - Chromium (Cr) has 24 valence electrons (based on its position in the periodic table). - The two thiolate (HS-) ligands each contribute one electron, for a total of 2 electrons. - The bidentate ligand (H₂O) has multiple atoms and bonds, but can be simplified as contributing 6 electrons. - The monodentate ligand (₆) also contributes 6 electrons. - The monodentate ligand (^3-) contributes 2 electrons. Adding these all up, we get: 24 + 2 + 6 + 6 + 2 = 40 valence electrons Therefore, the correct answer is E (18).
