If you have a molecule of NaOH and you are trying to figure out electron configurations (1s2, 2s2, 2p6 etc) Do you add an extra electron for Na because it now has a bonding electron or because its ionic wiill it lose that electron to OH in which case when figuring out OH's configuration do you add an eletron?

It is an ionic compound, that means electron has been transferred already
