A non-integer.
An integer is just a whole number, excluding zero. Any positive integer will always have an opposite just by placing a negative sign in front of the positive integer. You can also say that any negative whole number is an integer.
An example of an integer is... - 4 is the opposite of 4, 21 is the opposite of - 21.
That depends on how you define "opposite." It could be -89, 1/89 or something that isn't a number at all.
No. Integers and whole numbers are the same.
No. If it is an integer then it is a whole number.

An Integer
No. An integer is the same as a whole number.
A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.
Because that is how the opposite of a number is defined.
technically speaking yes the opposite of 5 is -5

an integer is a whole number
The additive opposite of the additive opposite is the number itself. The multiplicative opposite of the multiplicative opposite is the number itself, unless the number was 0, in which case the first opposite is not defined.
A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.
That depends on how you define "opposite." It could be -6, or 1/6 or something that isn't a number.
