Now in a countable infinite set what is the state of "alef" when we take the set from 0 to minus infinity? What happens in the mapping then? Besides what if we count from minus to plus Infinity? What happens then?

0 belongs to the set of whole numbers. The set natural numbers/counting numbers includes 1, 2, 3, 4 etc.

0 is not a natural number. The set of natural numbers begins with 1.
