WebPolyatomic ions. In this article, we will discuss polyatomic ions. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text {Na}^+ Na+, \text {Fe}^ {3+} Fe3+, \text {Cl}^- Cl−, and ... WebIon milling is a process by which inert gas ions from a broad beam ion source are accelerated towards the surface of a substrate to effect physical etching. The ion milling or sputtering is a physical process and does not have any chemical componet as opposed to reactive ion etching.
