What Are Monoatomic, Diatomic, and Polyatomic Elements?

TL;DR

Monoatomic elements consist of single atoms, such as helium and neon. Diatomic elements are made of two atoms, like hydrogen and nitrogen, while polyatomic elements feature multiple atoms, for example, tetranitrogen. Understanding these classifications helps in grasping the basic structures of chemical elements and ions.

what is the difference between a monoatomic element a diatomic element or even a polyatomic element or ion let's talk about that in this video so first let's make two columns the first one is going to be four elements and the other one is going to be for ions now let's talk about the monoatomic elements so if you look at the prefix of the word mono...
