The third electron will go on another side of the symbol: (2.9.6) B e ˙: Again, it does not matter on which sides of the symbol the electron dots are positioned. For carbon, there are four valence electrons, two in the 2 s subshell and two in the 2 p subshell. Web2. Indicate how many full and half-full orbitals there are in the valence shell of the following elements: (2 marks each) a) Radon (Rn) has 8 electrons in its valence shell, so it has 4 full orbitals. b) Lead (Pb) has 4 electrons in its valence shell, so it has 4 half full orbitals.
