Every single orbital is completely filled. And remember, every atom on a table wants to become a noble gas. So every atom wants to become or wants to take the electron configuration of a noble gas. And Neon is, in fact, a noble gas. Another way representing electro configurations are using noble gas configurations. Notice that one S, two, two S two and two P, six is identical to one S Two, two S two and two P six of Neon.
