are oppositely charged ions. For covalent bonding the particles are atoms which share pairs of electrons. For metallic bonding the particles are atoms which share delocalised electrons. Ionic bonding occurs in compounds formed from metals combined with non-metals. Covalent bonding occurs in non-metallic elements and in compounds of Metallic bonding occurs in metallic elements and alloys. Define ‘electrostatic forces’ of attraction. Describe the ions formed by metals and non-metals. Pupils cut out a nucleus, and add the symbol and proton number. Add electrons using split pins onto the correct energy level. Draw an electron dot diagram of the atom. Remove the valence electrons (or add more) to get to the nearest full energy level. Draw an electron dot diagram of the ion. Indicate whether the ion is positive or negative. 5.2.1.2 When a metal atom reacts with a non-metal atom, electrons in the outer shell of the metal atom are transferred. Metal atoms lose electrons to become positively charged ions. Non-metal atoms gain electrons to become negatively charged Draw dot and diagrams for ionic compounds formed by metals in Groups 1 and 2 with non-metals in Groups 6 and 7.
