AQA A-Level Chemistry – Bonding Verified Test 2023. Ionic Bonding - ANSWER A bond between metals and non-metals. The metal will donate electrons to the non-metal in order to achieve a full outer shell and achieving noble gas status. This allows the molecules to be ionised, forming attraction towards one another due to opposite charge attraction via electrostatic forces Ionic Lattice - ANSWER The structure of an ionic compound. This allows the compound to be brittle and non-conductive in a ...
