4.1 Ionic bonding and structure SL
• Positive ions (cations) form by metals losing valence electrons.
• Negative ions (anions) form by non-metals gaining electrons.
• The number of electrons lost or gained is determined by the electron configuration of the atom.
• The ionic bond is due to electrostatic attraction between oppositely charged ions.
• Under normal conditions, ionic compounds are usually solids with lattice structures.
• Deduction of the formula and name of an ionic compound from its component ions, including polyatomic ions.
• Explanation of the physical properties of ionic compounds (volatility, electrical conductivity and solubility) in terms of their structure.
