There is e- sharing going on in all chemical bonds, but not all bonds share e- equally.Electrons are _transfrred_ (shared/transferred) between a _metal_ and _nonmetal An ionic bond involves the _sharing_ (transfer/sharing) of electrons. A common misconception is the idea that elements tend to bond with other elements in order to achieve these octets because they are 'stable' or, even worse. In reality even the most classic examples of ionic bonding, such as the sodium chloride bond, contain characteristics of covalent bonding, or sharing of electrons of outer shell electrons. Metals tend to lose electrons to attain Noble Gas electron configuration. The most metallic elements are Cesium and Francium. Metals are the elements on the left side of the Periodic Table. Ionic bonding Ionic bonds form between metals and non-metals. Best computer desk under dollar50Chemical bonding leads to a lowering of the PE and formation of more stable chemical species. Ionic compounds form from positively charged ions (cations) and negatively charged ions (anions). Metals lose electrons and non-metals gain electrons. The compounds form when outer-shell electrons are transferred from the metallic atom to the non-metallic atoms. A discrete group of atoms connected by covalent bonds is called a molecule -the smallest part of a compound that retains the chemical identity of that compound. The sharing of electrons between atoms is called a covalent bond, and the two electrons that join atoms in a covalent bond are called a bonding pair of electrons. During covalent bonding, the electrons are shared between two atoms, and the atoms are bonded together by the sharing of the electrons (not the attraction between the opposite charges). This is the type of bonding that relates to polar vs nonpolar. Covalent bonding is a type of bonding that involves the sharing of electrons between atoms.Atoms that lose electrons become positively charged ions.

c) When atoms form chemical bonds by transferring electrons, they form ions.

Usually the elements involved are nonmetallic and have small electronegativity differences. Unlike ionic bonds where electrons are transferred, atoms bonded covalently share electrons. The other major bonding mechanism in ceramic structures is the covalent bond.
