In 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, [tex]p_x, p_y, and p_z[/tex]. How many degenerate orbitals are needed to contain six electrons with two of them unpaired? Express your answer numerically.
