???? Second Year Course - Formation of Monatomic Ions After discussing the electronic structure of an atom, we can now explain why some atoms gain or lose electrons to form ions (case of monatomic ions in this course). The other possibility to stabilize is to formulate molecules, studied with the Lewis model and the covalent bond. Capsules associated with this course: ???? The ELECTRONIC PROCESS of an atom: • How to find the ELECTRONIC PROCESS... ???? LEWIS model: covalent bond, bonding and non-bonding doublet • LEWIS model: covalent bond, ...
