Make a formula for a substance consisting of two oxygen atoms, show a diagram of its formation.

A compound containing two oxygen atoms is called molecular oxygen. The type of its bond is covalent non-polar, since there is no displacement of the electron cloud to one of the atoms (because two atoms have the same electronegativity). This connection is supported by the formation of common electronic pairs.
They write it like this: in the structural form O = O, since two electron pairs are formed, and in the electronic form – O :: O (the electronic form describes the behavior of electrons in the compound).
