Which group of the periodic table contains elements that exist as diatomic molecules?

Ah, diatomic molecules are like best friends that always stick together! Elements in Group 17, also known as the halogens, are the ones that exist as diatomic molecules in their natural state. They form pairs, like H2, Cl2, and Br2, creating beautiful bonds that make them feel cozy and complete. Just like how we all need a friend to feel whole, these elements find comfort in each other's presence.
