of our understanding of the structure of atom. New Zealand scientist Ernerst Rutherford was the first to show that the atom is the building block of all matter that consists of a positively charged nucleus surrounded by tiny negatively charged electrons. The extraordinary achievements of these scientists have been instrumental development of chemistry over the past century. Today‚ we take the existence of atoms for granted. We can explain many aspects of the structure of the atom and in fact‚ current

Three bombs were created‚ "Trinity"‚ "Little Boy"‚ and "Fat Man". "Trinity" was dropped on a test site in New Mexico on July
