When did the nuclear bomb explode?

Answer 1

In war: August 6, 1945 and August 9, 1945. They have never been used since.

In peacetime: some were dropped, some were detonated on the ground, some were detonated under the ground, some were detonated under water, some were detonated on steel towers, some were detonated hanging below balloons, some were detonated in the air after being shot from artillery pieces, some were detonated in the air on rockets fired from fighter intercepter planes, some were detonated high in the atmosphere or in space carried there on rockets, etc.

The first post WW2 tests were in the summer of 1946: Crossroads Able was dropped from a B-29. Crossroads Baker was suspended underwater from a barge in the center of Bikini lagoon. Due to unanticipated contamination from the Baker shot, the Crossroads Charlie shot was canceled.

Although most major powers (particularly the US and Russia) have ceased all nuclear tests, testing continues today by other nations.

Answer 2

The first 5:

1. July 16, 1945: Trinity test
2. August 6, 1945: Hiroshima Japan
3. August 9, 1945: Nagasaki Japan
4. July 1, 1946: Bikini atoll, Crossroads Able test
5. July 25, 1946: Bikini atoll (underwater), Crossroads Baker test

After Crossroads Baker, the entire US (and world) stockpile of nuclear weapons consisted of 4 bombs. Testing continued in 1948 (Sandstone), then after the soviet test in 1949 the US opened the Nevada test site in 1951 and both the US and USSR did nearly annual above ground testing until 1963. Then it went below ground.

Answer 3

The last Atomic bomb was dropped on the 9th August 1945 on Nagasaki by the USA. It was also the last major act of WW2 before the Japanese surrendered.

Answer 4

That has yet to occur, so I can't say.
