Practise IB Chemistry HL 2.1.3 by explaining lattice and ion mobility, comparing salt properties and interpreting data on solubility, conductivity and salt formation.
Magnesium is a group 2 metal which exists as a number of isotopes and forms many compounds.
Describe the structure and bonding in solid magnesium oxide.
«3-D/giant» regularly repeating arrangement «of ions»
OR
lattice «of ions»
electrostatic attraction between oppositely charged ions
OR
electrostatic attraction between Mg^2+ and O^2- ions
Marking guidance:
Accept "giant" for M1 unless "giant covalent" stated.
Do not accept "ionic" without description.
