How many outer energy level valence electrons does the sodium atom have?

Ok, here we go...
Sodium has 11 protons and 11 electrons, because they are always equal. This means that in its innermost electron shell is full, having 2 electrons, and so is the next shell, with 8. 8+2=10, so there is one lonely electron in the outer valence shell. This means Sodium has a valence of 7, or it desires 7 electrons to complete its valence shell, because 8 (number the third shell can hold) - 1 (number actually in it) = 1. An electron with a completed valence shell is more stable than one without. This is why carbon is so versatile. Remember: the valence of an atom equals the number of protons the valence electron shell can hold minus the number actually in it.
Also, a little known fact about the Periodic Table...
Each row represents how many electron shells the element has. For instance, all elements in the third row have three shells.
