Lots of prime numbers have zeros in them. 101, 103, 107 and 109 are all prime numbers. Prime numbers can't end in zero. Numbers that end in zero are multiples of ten and have too many factors to be prime numbers.
Square numbers can't be prime. They have too many factors.
5 is a prime number,because prime numbers only have too numbers that go into itself.those numbers are 1 and itself, in this case 5. with composite numbers it is the other way around.
