Atomic Structure. Ionic compounds When a metal element reacts with a non-metal element an ionic compound is formed. Ionic compounds include salts, oxides, hydroxides, sulphides, and the majority of inorganic compounds. For example, the sodium ions attract chloride ions and the chloride ion attracts sodium … An atom of sodium (Na) donates one of its electrons to an atom of chlorine (Cl) in a chemical reaction, and the resulting positive ion (Na +) and negative ion (Cl −) form a stable ionic compound (sodium chloride; common table salt) based on this ionic bond. Sodium chloride has a giant ionic lattice. To better understand why and how ions — atoms that have a charge due to the loss or gain of electrons — are formed, you can study what happens during the chemical reaction to create salt. The sodium metal is said to be oxidized. Lewis electron dot symbol to describe ionic bonding in sodium chloride. The components: sodium and chlorine . the formation of sodium and chloride ions that are infinitely far apart—in other words, the positive energy change assumes that the ions do not interact with each other, which is quite different from the situation in ionic solids. Describe this reaction in terms of electrons. When an atom of chlorine reacts it will gain one electron from sodium.The outer shell of chlorine will then have 8 electrons and be full.The chloride ion will have an extra electron and therefore an extra negative charge (shown as a - sign). An understanding of the way the elements are bonded allows us to explain their typical properties. These charged atoms are called ions. It is in group 7 of the periodic table.. The principal reason ionic compounds are stable is the attraction between ions of opposite charge. cation). Q7: Sodium atoms react with chlorine atoms to form sodium chloride. Sodium will lose an electron to become Na + whilst chloride will gain an electron to form Cl-. Ionic bonding in sodium chloride. The formation of sodium chloride involves sodium metal, Na and chlorine gas, Cl 2. (4 marks) Click to reveal the correct answer. This is formed due to the ionic bonding, which involves the transfer of electrons from one atom to another to ensure each atom has a full outer shell of electrons. The reaction can be thought of involving the following simultaneous processes: The oxidation of sodium metal; Sodium atoms lose its outer-shell electron to become a sodium ion, (i.e. [FT] Ion Formation . Ionic solids are held together by the electrostatic attraction between the positive and negative ions. For an ionic bond to form you need a metal (to donate electrons) and a non-metal (to gain electrons). The process of creating table salt is pretty remarkable. This is shown in the diagram to the right. The Reaction between Sodium and Chlorine.. Chlorine has 7 electrons in its outer shell. Ionic bonding is the type of bonding that holds salts together.
