Recall that nitrogen has five valence electrons and therefore requires three electrons or bonds to complete its octet (see Amine Tutorial). Based on this valence and bonding order, nitrogen forms three bonds in its neutral state and maintains one pair of non-bonded electrons (NBEs). In amides one of the three bonds is a carbonyl carbon. Thus amides may be viewed as "acylated amines" or as deriv...
