Think about This!

It may be hard to visualize atoms coming together to form molecules or compounds. An easier way to picture it is to imagine tinker toys. The balls represent the atoms, and the sticks represent the bonds that hold them together. Scientists have their own special set of tinker toys to represent how molecules look. They are called molecular model kits. Below is a picture of a representation of a catalyst molecule that contains a transitino metal. It was made from a scientist's model kit. The different colored balls represent atoms of different elements. The black balls represent carbon atoms, the blue balls represent oxygen atoms, the white balls represent hydrogen atoms, and the center, gray ball represents a palladium atom. Each white stick represents a single bond between two atoms, while two blue curved sticks represent a double bond between two atoms.
