Equivalence of and Orbitals

There are 24 valence electrons iij BFs [7 from each fluorine (Zs lp ), 3 from the boron (2r 2fi)]. Placing these electrons in the most stable molecular orbitals, we obtain a ground-state configuration  

There are six electrons in a orbitals to give a total of three a bonds for BFs in addition, the two electrons the r/ orbital indicate one tt
