Explain how ionic bonds are formed by the transfer of electrons between atoms to produce cations and anions, including the use of dot and cross diagrams

Recall that an ion is an atom or group of atoms with a positive or negative charge

Calculate the numbers of protons, neutrons and electrons in simple ions given the atomic number and mass number

Explain the formation of ions in ionic compounds from their atoms, limited to compounds of elements in groups 1, 2, 6 and 7

Explain the use of the endings -ide and -ate in the names of compounds

Deduce the formulae of ionic compounds (including oxides, hydroxides, halides, nitrates, carbonates and sulfates) given the formulae of the constituent ions

Explain the structure of an ionic compound as a lattice structure

a) consisting of a regular arrangement of ions
b) held together by strong electrostatic forces (ionic bonds) between oppositely-charged ions
