This PPT contains DP Chemistry PPT materials for both SL and HL about “ Structure 2.1: Ionic Model” based on the 2023 IB DP Chemistry curriculum. Here are the materials and objectives that will be covered in this sub-topics: 2.1.1 Ions When metal atoms lose electrons, they form positive ions called cations. When non-metal atoms gain electrons, they form negative ions called anions.2.1.2 Ionic BondThe ionic bond is formed by electrostatic attractions between oppositely charged ions.Binary ioni
