With conventional explosives to assemble a supercritical mass before it can begin a spontaneous chain reaction, melt and fizzle. Then a neutron source sprays the supercritical mass with a burst of neutrons at the optimal time to trigger a high efficiency chain reaction. The conventional explosives were detonated with electrical exploding wire detonators.
No. Hydrogen Bombs have been detonated that make the atomic bomb look small in comparison. The Atomic Bombs dropped on Japan in WW2 were 25 Kton (equivilent to 25000 tons of dynamite), while H bombs can be as big as several hundred Megaton (million tons of dynamite)

Yes, the first was detonated by the U.S. in 1952.Codename Mike as part of Operation Ivy, it had a yield of 10.4 megatons(450 times as powerful as the bomb dropped on Nagasaki)and was detonated at Eniwetok atoll in the Marshall islands.
Depends on yield and where detonated.
The atomic bomb is an artefact, and so an invention. Maybe you meant to ask who invented the atomic bomb ?
The first atomic bomb detonated was not dropped, it was hung from the top of a steel structure and detonated remotely.
USSR
It is not , if it is not detonated and it is properly maintained.
Trinity Site, NM, 1945
The atomic bomb was detonated in 1945.
The atomic bombs did not land, they were detonated 2000 feet in the air above Hiroshima and Nagasaki.
The first atomic bomb was detonated on the city of Hiroshima, Japan
The US needed a place to test the bomb, and the desert in New Mexico was the best place.
Trinity site near Alamogordo, New Mexico.
By cables from a bunker 10,000 yards south from the tower that held the Gadget.
Hiroshima was the first to be bombed in World War 2.
On August 9, 1945, the "Fat Man" nuclear bomb was detonated over Nagasaki.
