Sodium Chloride, NaCl. The classic case of ionic bonding, the sodium chloride molecule forms by the ionization of sodium and chlorine atoms and the attraction of the resulting ions. An atom of sodium has one 3s electron outside a closed shell, and it takes only 5.14 electron volts of energy to remove that electron. The chlorine lacks one electron to fill a shell, and releases 3.62 eV when it acquires that electron (it's electron affinity is 3.62 eV).
The bond form in Sodium cloride (NaCl) is Ionic bond, due to the fact that Sodium (Na) is a metal element and Chlorine (Cl) is a non-metal element.When both of them a â¦ re chemically combine together, they form a giant lattice sturcture which is a ionic bond.1 person found this useful.lements It is simply consists one kind of element, it's the simplest structure and can be form into molecule or singl â¦ e atom (O2, N2 and ecetra) mixture It's simply consist of 2 or more kind of element that are physically mix or intermingle. the properties still remain like its component.
