WebThe Geiger–Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. They deduced this after measuring how an alpha particle beam is scattered when it strikes a thin metal foil. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/bohr.html

Web28 aug. 2015 · Explanation: When atoms are heated, electrons will move from their ground state (lower energy level) to a higher energy level. This process is called excitation. It requires energy. Once the electrons are at higher energy levels, they don't stay there forever. They will eventually fall back down to their original energy level (ground state). WebWhen the star compounds inside a firework are heated, the excited atoms give off light energy. This light falls into two categories: incandescence and luminescence. Incandescence is light produced from heat. In fireworks, reactive metals (aluminum or magnesium) cause a burst of very bright light — sometimes at temperatures over 5000° F!
