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. Sodium will lose an electron to become Na + whilst chloride will gain an electron to form Cl-. [FT] Ion Formation . Ionic compounds When a metal element reacts with a non-metal element an ionic compound is formed. Q7: Sodium atoms react with chlorine atoms to form sodium chloride. Ionic compounds include salts, oxides, hydroxides, sulphides, and the majority of inorganic compounds. 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). (4 marks) Click to reveal the correct answer. Lewis electron dot symbol to describe ionic bonding in sodium chloride. Ionic bonding in sodium chloride. The formation of sodium chloride involves sodium metal, Na and chlorine gas, Cl 2. Describe this reaction in terms of electrons. The sodium metal is said to be oxidized. Sodium chloride has a giant ionic lattice. 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. Ionic solids are held together by the electrostatic attraction between the positive and negative ions. 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. 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. The Reaction between Sodium and Chlorine.. Chlorine has 7 electrons in its outer shell. The components: sodium and chlorine . An understanding of the way the elements are bonded allows us to explain their typical properties. Ionic bonding is the type of bonding that holds salts together. For an ionic bond to form you need a metal (to donate electrons) and a non-metal (to gain electrons). The principal reason ionic compounds are stable is the attraction between ions of opposite charge. It is in group 7 of the periodic table.. The process of creating table salt is pretty remarkable. These charged atoms are called ions. 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. For example, the sodium ions attract chloride ions and the chloride ion attracts sodium … cation). This is shown in the diagram to the right. Atomic Structure.
