Well to correct your grammar first of all so I can read the question more understandably, what is a whole number and its opposite. A whole number is a number greater than 0. The opposite of a whole number is a negative number. A negative number is a number below 0, like you see on thermometers when its really cold sometimes. Here is a very important thing that you need to know. If you don't know this you will get it wrong on a test. 0 is not a negative number or whole number. It is just known as a place holder on the number line.
An Integer
They are a pair of opposite whole numbers. Except in the case of 0 whose additive opposite is itself and which does not have a mulitplicative opposite.
No.
Apart from zero (which is its own opposite), the opposites of whole numbers are also whole numbers. You have the set of whole numbers which is also known as the set of integers.
They are 0 which is its own additive opposite. 0 does not have a multiplicative opposite.
if the opposite you are saying is the inverse, then the answer is no.
What exactly do you mean when you say "the opposite of a whole number" . . .
The opposite of an even number is an odd number.
It's opposite is a negative. :P
Whole number
An Integer

No.
The square root of 16 is 4 which is a whole number.
technically speaking yes the opposite of 5 is -5
Apart from zero (which is its own opposite), the opposites of whole numbers are also whole numbers. You have the set of whole numbers which is also known as the set of integers.
It would be 0, which is also its opposite.
