The element oxygen forms molecules that each contain two oxygen atoms. The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms. Which statement is true?

The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms is TRUE.

Explanation:

The elements carbon and oxygen form molecules that each contain one carbon atom and two oxygen atoms is true because a compound can only be formed from the combination of two or more elements but not from one element.

The molecule formed from one carbon element (C) and 2 oxygen elements (O) is CO2. CO2 which is known as carbon (IV) oxide is a compound which is made up of carbon and oxygen elements.
