Ions and Ionic BondsDescribe the formation of positive ions, known as cations, and negative ions, known as anionsState that an ionic bond is a strong electrostatic attraction between oppositely charged ionsDescribe the formation of ionic bonds between elements from Group I and Group VII, including the use of dot-and-cross diagramsDescribe the properties of ionic compounds: high melting points and boiling points, good electrical conductivity when aqueous or molten and poor when solidDescribe the giant lattice structure of ionic compounds as a regular arrangement of alternating positive and negative ionsDescribe the formation of ionic bonds between ions of metallic and non-metallic elements, including the use of dot-and-cross diagramsExplain in terms of structure and bonding the properties of ionic compounds: high melting points and boiling points, good electrical conductivity when aqueous or molten and poor when solid
