Natural numbers are positive counting numbers. There is no general consensus on whether or not 0 is a counting number. It is also unclear if you mean between -3 and 3, inclusive of -3 and 3, or not inclusive.
Thus there are four possible answers to this question.
If 3 is allowed, and if 0 is a counting number:
{0 , 1 , 2 , 3}
If 3 is not allowed and if 0 is a counting number:
{0 , 1 , 2}
If 3 is allowed and 0 is not a counting number:
{1 , 2 , 3}
If 3 is not allowed and 0 is not a counting number:
{1 , 2}

Does that include 3 or not?
In first case, the natural numbers are 1,2,3.
In the second case, the natural numbers are only 1,2.

1,2 and 3 are its only elements.
The set is {1,2,3}.
0 is not a natural number.
-3,-2,-1 are integers but not whole numbers.

{1, 2}
i'm pretty sure it's one of those.
natural numbers = positive integers = all positive numbers without decimals.
a set is a group of numbers.

did you mean between those numbers or including those numbers?
between = {1,2}
including = {1,2,3}
a natural number is an integer greater than or equal to 1.
1,2,3,4,5,6,7,8,9,10 ect. those are all natural numbers.
