Practicing Success
The number of unpaired electrons in \(Fe^{+2}, Mn^{2+}, Cr^{3+}, V^{5+}\) and \(Cu^{2+}\) are respectively? |
\(4, 5, 3, 0, 1\) \(5, 4, 3, 0, 1\) \(4, 5, 3, 1, 1\) \(5, 5, 3, 0, 1\) |
\(4, 5, 3, 0, 1\) |
The correct answer is option 1. \(4, 5, 3, 0, 1\) The ground-state electronic configuration of iron\((Fe)\) is
The configuration of \(Fe^{2+}\) is The number of unpaired electrons = \(4\) The ground-state electronic configuration of manganese\((Mn)\) is The configuration of \(Mn^{2+}\) is The number of unpaired electrons = \(5\) The ground-state electronic configuration of chromium\((Cr)\) is The configuration of \(Cr^{3+}\) is The number of unpaired electrons = \(3\) The ground-state electronic configuration of vanadium \((V)\) is The configuration of \(V^{5+}\) is The number of unpaired electrons = \(0\) The ground-state electronic configuration of copper \((Cu)\) is The configuration of \(Cu^{5+}\) is The number of unpaired electrons = \(1\)
