Within the continental US there have been just short of 1000 nuclear detonations for various purposes, over 95% of these were within the Nevada Test Site just north of Las Vegas, NV. This does not include safety tests, plutonium dispersal tests, RaLa tests, etc. that produced no nuclear yield but were experiments required for bomb development.
There were many thousands of people that worked on the project in various locations. The scientist in charge was Robert Oppenheimer.
US estimates suggest that 4.7 square miles of Hiroshima were destroyed.
The US began the development of the atomic bomb during World War II as part of the top-secret Manhattan Project in response to the fear that Nazi Germany was also working on developing such a weapon. The US sought to maintain a technological advantage and end the war quickly by possessing this powerful weapon.
The first US weapon utilizing laydown delivery was the Mark 15 bomb, and was the first "light weight" thermonuclear bomb. The Mark 7 bomb was delivered using the loft bombing, a similar technique to laydown, but laydown delivery and lob delivery are not one-and-the-same for various reasons including the use of a retarding parachute on the bomb during laydown, and the attitude of the aircraft when the weapon is released.
The model of an atom is larger than the actual atom itself. Atom models are simplified representations used to help understand the structure and behavior of atoms at a scale that is easier for us to comprehend.
