Got a Periodic Table?.............

Explanation:

Z=11, "sodium"; the nearest Noble Gas on the Table has Z=10. So when sodium is oxidized it should have an equal number of electrons to .......?

On the other hand, for chlorine, Z=17. Upon reduction, this atom is isoelectronc with the nearest Noble Gas on the Table, for which Z=18.

Are you happy with this?
