Atoms, Elements & Molecules, Models Unit molecular model kit (basic set), 1981. Made by Cochranes of Oxford Ltd. Each ball represents an atom of a chemical element, and can be connected to other ÔatomsÕ by means of bonds represented by inserting the connecting pegs in holes in the balls. The number of holes in a ball represents the number of molecular bonds atoms of different elements are able to form. This is determined by an elementÕs valency, which is dictated by the number of electrons in the outermost shell of an atom of that element. ©SSPL/Science Museum
