However, scientists discovered about that time that a powerful explosion might be possible by splitting an atom. This type of bomb could destroy large cities in a single blast and would change warfare forever!. , Austin. Dalton’s Atomic theory. John . D. alton (1766-1844) developed an atomic theory that proposed that atoms were responsible for the combinations of elements found in compounds.. Who was he?. by . Tiffany, Katelyn, Veronica, . Kole.

Science is based off of observations.. A Scientific Law is a summary of what is seen in observations. . A Scientific Theory is an explanation of why these observations are occurring.. Both laws and theories are tested by using them to predict what would happen in certain situations.. How and why has the Atomic Theory changed over time? .
