Orbital Diagram Orbital Diagrams give a more complete indication of the electron quantum numbers.  Each orbital represented by a box and each electron by a half-arrow. For example  Hydrogen  has 1 electron. That electron goes into the lowest energy orbital,  that is the 1s orbital. Thus we write. .. For  Boron  we start with 5 electrons. Again we start by filling the lowest energy orbital  1s, then the 2s orbital, and finally putting one electron in the 2p orbital. .. Now let's look at  Carbon , which has 6 electrons. Hund's Rules:  Electrons occupy different orbital or a given subshell with spins in  the same direction before spin pairing occurs. Therefore for carbon we have

Another example,  Neon  has 10 electrons. For Neon, both the n=1 and n=2 shells are completely full. Let's look at
