First, what do you mean by finish?
The nuclear reaction that produces the explosion completes in a few microseconds (less than 20 microseconds in my computer simulations). The fireball took a few seconds to expand to maximum size. The mushroom cloud took from 2 to 5 minutes to rise to its maximum altitude. Fallout took hours to months to descend depending on altitude, wind, precipitation, etc. (fallout from the top of the mushroom cloud often was caught in the jet stream and carried around the earth hundreds of times, this sometimes stayed up for years)

Where did testing of the atomic bomb take place?
The atomic bomb was tested at the Trinity site in Alamogordo, New Mexico in 1945.
How long did it take the atomic bomb to hit the ground?
If you are asking specifically about the two bombs dropped on Japan in WW2, they were fuzed for airburst, so they did not hit the ground. Both exploded between 1500 ft & 2000 ft altitude. Airburst was selected to maximize blast & thermal flash damage effects area.
How long did it take to make the atomic bombs used in World War 2?
The US was capable of producing 3 atomic bombs a month at the end of WW2. This would suggest it took a bit over a week to make each bomb kit. However it isn't that simple, the 3 bomb per month bottleneck was the Hanford plutonium production reactors: each of the 3 reactors could make 1 bomb worth (6.2 kg) of plutonium a month and they ran in parallel.
What causes an atomic bomb not to explode immediately?
A timer controlling when neutrons willl be lanuched and absorbed by the atom bomb...therefore contolling when a critical mass will be reached and when a nuclear raection will take place leading up to the explosion. <22> The nator geniuzzz <22>
How long does it take for a nuclear bomb to clear up?
That is complicated:Depends on yield and height/depth of burst.Depends on several features of bomb design.Depends on halflives of radiological contaminants produced.Depends on decontamination effort attempted and degree of success.Depends on weather.
