No. Natural numbers may or may not include 0, depending on who you ask (i.e. they can begin 0, 1, 2, 3, … or 1, 2, 3, 4, …), but they don't ever include the negative numbers. However, integers, which are a superset of the natural numbers (i.e. the natural numbers are contained "in" the integers), do include negatives.

even, whole, non-negative numbers. (zero is not a natural number)
What is a number that is an integer but is not a natural number?
Negative numbers are not natural, but there are negative integers. Examples are -1,-2,-3,-4, and so on. These are all integers but none of them is a natural number.
Are All rationals numbers are in the set of natural numbers?
1. No.The Natural numbers are the positive integers (sometimes the non-negative integers).Rational numbers are numbers that can be expressed as the quotient of two integers (positive or negative). All Natural numbers are in the set of Rational numbers. 2. No. Natural numbers are usually defined as integers greater than zero. A Rational number is then defined simply as a number that can be expressed as an integer divided by a natural number. (This definition includes all rational numbers, but excludes division by zero.)
Is -7.3 a natural number?
No, -7.3 is not a natural number. Natural numbers are whole numbers greater than zero, so they cannot be negative or contain decimals. The set of natural numbers is typically denoted as {1, 2, 3, ...}. Negative numbers and decimals fall under different categories, such as integers and real numbers, respectively.
Which number is not common between natural numbers and whole numbers?
Zero is a member of the set of whole numbers. Some people include it in the set of natural numbers, some people don't.
