In these oxides, all the outer electrons in the Period 3 element are being involved in the bonding - from just the one with sodium, to all seven of chlorine's. The alkene derivatives can be prepared from the corresponding aldehyde or ketone. In fact, such an assumption seems to be arbitrary, and likely to be an erroneous reference for both the BEs and chemical shifts of Fe core-levels.
