For example wikipedia says, Wikipedia ref: . From the periodic table, we see that the atomic number (number of protons) for the element carbon is #6#. Because of the nature of quantum mechanics, no single image has been entirely satisfactory at visualizing the atoms various characteristics, which thus forces physicists to use complementary pictures of the atom to explain different properties. The chemical symbol for carbon is #"C"#. Chemical symbols are used to standardize the 'language of chemistry' and to identify elements and atoms in a chemical formula easily. This type of munition is capable of producing massive amounts of intense fire.
