No, whole numbers are defined as non-negative integers.

Which of the following sets of numbers contains ONLY integers?
You did not provide any choices to choose from, but you can tell this way. Integers include whole numbers (which are the counting numbers and zero) and their negatives. So -5, 0, 1, 5023, -5435345435, are all integers. No fractions or decimals are included in the set of integers.
Which expression represents an irrational number?
It is not always easy to tell if a number is irrational. If a number can be expressed as a ratio of two integers, then it is rational. If not, it is irrational. So the expression is in the negation: a number than cannot be expressed as a ratio of two integers.
