n the molecule SCl2, sulfur makes two covalent bonds. Therefore, two of its six valence electrons need to be unpaired. The orbitals with the same energy are known as degenerate orbitals. For example, the p subshell has three degenerate orbital, namely, px, py, and pz. How many degenerate orbitals are needed to contain six electrons with two of them unpaired? Express your answer numerically.
