The term for positive and negative whole numbers, including zero, is "integers." This classification encompasses all whole numbers such as -3, -2, -1, 0, 1, 2, and 3, among others. Integers are significant in various mathematical contexts because they include both the positive and negative variations of whole numbers along with zero, effectively illustrating the complete set of whole numbers on a number line.

The other categories do not include both positive and negative numbers. Rational numbers include fractions and whole numbers but extend beyond just integers. Whole numbers consist only of non-negative integers (0 and positive whole numbers). Natural numbers start from 1 and do not include zero or negative numbers. Thus, the definition of integers correctly captures the desired set of numbers: positive whole numbers, negative whole numbers, and zero.
