AQA A-Level Chemistry – Bonding Practice Questions 2022-2023.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-conducti...

Metallic bonding electrostatic attraction between postive ions and delocalised electrons Ionic bonding strong electrostatic attraction between oppositely charged ions Covalent bonding strong electrostatic attraction between two nuclei and the shared pair(s) of electrons between them Atomic number Number of protons Mass number number of protons and neutrons Malleable Can be hammered into shape Ductile Can be drawn into a wire Electronegativ...

Ionic bonding Strong electrostatic attraction between oppositely charged ions What effect does ionic radius have on the strength of ionic bonding? The smaller the radius, the stronger the strength of the ionic bond. What effect does ionic charge have on the strength of ionic bonding? The higher the charge (the number) of the ions involved, the strong the ionic bond. Covalent bonding The strong electrostatic attraction between a shared pair of electrons and the nuclei of ...
