Witryna15 mar 2024 · 1.Ball-and-stick models . Ball-and-stick models use spheres to represent atoms and sticks to represent chemical bonds. The advantage of ball-and-stick models is that they show the correct angles between the bonds. However, the relative sizes of the spheres do not always match the relative sizes of the atoms they … WitrynaThe chemist Wilhelm August Hofmann first used coloured balls to represent the elements around 1865. John Dalton, who in the 19th century made great advances in thinking about the structure of atoms, used ball and spoke models in his lectures.
