A banana. It is not even a number so it is a brilliant non-example.
There is some disagreement as to whether zero, a whole number, belongs to the set of natural numbers.
Natural numbers are the numbers used to count things 1, 2, 3, 4.... Etc. There is some debate if zero should be included with the natural numbers. They are also used to order things first, second, third etc. "The box contains 20 apples" would be an example of natural number usage.
is a natural number a whole number
All natural numbers are also real numbers, but all real numbers are not necessarily natural numbers because natural numbers are positive whole numbers. Real numbers are any number on the number line, which includes irrational numbers like pi and sqrt2. Thus only the positive natural numbers are both natural and real. Hope this is not too long-winded!
True
true
I think so yah
Yes

True. Zero is in the set of whole numbers, integers, rational numbers and real numbers but not natural numbers. Natural numbers are often referred to as the "counting numbers" or how you learned to count. When we are teaching little children numbers, we never start with zero or negative numbers - just 1, 2, 3...
Isotopes are elements that have the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, Carbon-12 and Carbon-14 are isotopes of carbon.
No. A simple example is 5 - 6 = -1. Two natural numbers (5 and 6) are used to subtract to -1 (which isn't a natural number).

On the Periodic Table, there are two numbers for every element: the atomic number and the atomic weight. The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number. For example, the atomic number for the element Krypton is 36. That means that there are 36 protons in the nucleus. If there were not 36 protons in the nucleus of that atom, that would create the atom of a completely different element. For example, if one proton was to be removed from the nucleus of the atom for the element of Krypton that atom will be an atom of the element bromine. The number at the bottom of the square represents the number of particles present in the atom's nucleus of that element. This is known as the atomic weight. For example, the atomic weight for the element Krypton is 83.80.
