![]() You will learn a lot more about atoms and molecules, including how they were discovered, in a later part of the textbook.Your class will be engaged as they learn all about matter. Each of these molecules has its own set of chemical properties, and it's these properties with which chemists are most concerned. There are millions of different ways to bond atoms together, which means that there are millions of different possible molecules. Molecules are groups of two or more atoms that have been bonded together. The most important method that nature uses to organize atoms into matter is the formation of molecules. ![]() In some ways, it's sort of like cooking a gourmet, five-course meal using only three ingredients! How is it possible? To answer that question, you have to understand the ways in which different elements are put together to form matter. At this point, what should amaze you is that all forms of matter in our universe are made with only 118 different building blocks. ![]() A substance that is composed of only one type of atom is called an element. Scientists have given a name to each different type of atom. ![]() These building blocks are known as atoms, and so far, scientists have discovered or created a grand total of 118 different types of atoms.
