Question

atomicity if oxygen is ___ and that of carbon dioxide is ____​

Answer 1

Answer:

Atomicity is defined as the total number of atoms present in a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2.[1] In older contexts, atomicity is sometimes used in the same sense as valency. Some authors also use the term to refer to the maximum number of valencies observed for an element.[2]
