Atoms are the basic building blocks of all matter. If you want to create a language, you need an alphabet. If you want to build proteins, you need amino acids and if you want molecules, you need to have atoms of different elements. Each element is a little bit different from the others. Those elements are the alphabet from which molecules are created.







Molecules are groups of atoms bonded together in the same way that words are groups of letters. An "A" will always be an "A" no matter what word it is in. A sodium (Na) atom will always be a sodium atom no matter what compound it is in. While the atoms may have different mass and organization, they are all built with the same parts. Electrons, protons, and neutrons make the Universe the way it is.









Atoms combine together to create the molecules around us. The 120 known types of elements also implies 120 types of atoms that can be found in the molecules we know. Smaller molecules can also work together and build macromolecules. It just goes on like this. Everything we see is built from something else. As you can see, all nature is ultimately made up of atoms.

In a book, you find many words on a page. Different letters make up those words. In English, we have just 26 letters, but we can create thousands of words. Similarly, we work with around 120 elements and combining them, we can create millions of molecules.
