As far as positive numbers are concerned, the additive inverse of a positive number is a negative number with the same magnitude (i.e. the additive inverse of 5 is -5). It would be wrong to simply say that "negative" and "additive inverse" are correct, because the additive inverse of a negative number is a positive number.
There is a complement that when added equals one but you may be thinking of multiplying. A number times its reciprocal (multiplicative inverse) is equal to one. A number added to its additive inverse (opposite) is equal to zero.
