1.32 explain, using dot and cross diagrams, the formation of ionic compounds by electron transfer, limited to combinations of elements from Groups 1, 2, 3 and 5, 6, 7

ELECTRON TRANSFER:

- In dot and cross diagrams it doesn't matter what element has a dot or cross you just have to make sure that one element either gains or loses electrons. In this case sodium is a cation and chlorine an anion.
