The Atomic Bomb was not "discovered". It was designed and created.
The first atomic bomb, "Little Boy," contained uranium-235 as its radioactive isotope.
The United States
The second atomic bomb was used on Nagasaki because Japan did not surrender after the first bomb on Hiroshima. The goal was to force Japan to surrender quickly and end World War II.
The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.
