2 is a prime number. A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. In the case of 2, the only divisors are 1 and 2, which fits the definition of a prime number perfectly.
On the other hand, a composite number is a natural number that has more than two positive divisors. For example, the number 4 is composite because it can be divided by 1, 2, and 4.
Additionally, 2 is unique as the only even prime number. All other even numbers can be divided by 2, making them composite. Therefore, 2 stands out in the list of prime numbers and is celebrated for this unique property.
