All ordinary matter in the universe is made up of protons, neutrons and electrons combined in different kinds of atoms to form elements, and as such, they cannot be simplified or chemically broken into smaller pieces. This episode of the Show Me Science series, Atoms and Elements takes a look at these building blocks and how they can be combined, through various chemical processes to create compounds. Viewers will also learn how we produce elements out of natural occurring materials, and see a “reality based experiment showing how forensic scientists identify basic materials to prove or disprove evidence against possible criminals.
