Synopsis
Spec references J248: C2.2di, C2.2e, C2.2f J250: C2.2di, C2.2e, C2.2f. Ideal for topic revision, this video explains how ions are formed through the loss and gain of electrons. It covers the differences in how metals and non-metals react, focusing on electron transfer. The video also explains how ion charges result from an imbalance between protons and electrons and relates the charge of ions to their group number. Additionally, it introduces the concept of ionic bonding, emphasising electrostatic forces of attraction and the use of dot and cross diagrams. A brief introduction to ionic formulae is also provided.
