Because negative numbers like -1 and -2 can't be whole be they are less than nothing. Just like you can have -1 pies or -1 people.

Zero is called the smallest whole number because it is the starting point of the number line. It is less than all positive whole numbers and is considered the lowest value in the set of whole numbers. Additionally, zero is the additive identity, meaning that when added to any number, it does not change the value of that number.
Yes, zero is the smallest whole number. One is the smallest counting or natural number.Another opinion0 (called "zero" or "nil") means "nothing exists" so 0 cannot itself be a real number.So the smallest whole number is 1. (Also known as "one" or "unity".)
The smallest whole number is 1. (Also known as "one" or "unity".)0 (called "zero" or "nil") means "nothing exists" so 0 cannot ever be a real number.In other words 0 certainly cannot be the smallest whole number because it simply is not a real number of any kind.
An integer is a whole number. So zero could be the smallest integer.
The best answer I think is "zero." It's usually included as the smallest of the whole numbers.There are different opinions about this. Here are some of them:0 (called "zero" or "nil") means "nothing exists" so 0 cannot be a real number at all. So the smallest whole number is 1. (Also known as "one" or "unity.") Because it is the "magnitude" or "size" of the number which is being asked about in this kind of question - and not its "polarity" or "sign," the previous sentence remains true no matter whether we are considering positive or negative whole numbers.Apparently mathematicians can use different definitions here, so there is no single "correct" answer. Certainly "zero" CAN BE INCLUDED in the "whole numbers" by some mathematicians.Some mathematicians say you can have negative whole numbers, but mostly they say you can't.
That really depends what numbers you are considering.If you consider the set of natural numbers, starting with zero, then no: the smallest even number is zero.If you exclude zero, and start counting at 1, then yes, two is the smallest even number.If you consider the set of integers (i.e., both positive and negative whole numbers), then there is no smallest even number.
