No. Jupiter's atmosphere is mostly hydrogen, which is flammable, but since there is virtually no oxygen in Jupiter's atmosphere combustion is not possible.
Not quite sure what you mean by "ignite the atmosphere"; I am pretty sure that it would not be able to provoke a runaway chain reaction, if that's what you mean.
Well there is no "Megaton" bombs, but there are hydrogen bombs in the megaton range and they are a lot more powerful. An Atomic bomb can destroy a city. A Hydrogen bomb can destroy a country.

our sun conversion pressure which is 600 millions tons of hydrogen to 595 millions tons of helium per second
It depends how big the explosion is. A stick of dynamite exploding on the moon would obviously not be visible to a naked eye on Earth, but a 100 Megaton hydrogen bomb might be.
atom bomb
The 50 Megaton "Tsar Bomba" hydrogen bomb tested by the USSR in 1961 is the strongest hydrogen bomb ever detonated. The 10 Megaton "Ivy Mike" hydrogen bomb tested by the U.S. in 1952 is the physically largest hydrogen bomb ever detonated.

The most powerful hydrogen bomb ever built had a 50 megaton yield (USSR "Tsar Bomba" 1961), the most powerful hydrogen bomb ever built by the U.S. had a 20 megaton yield ("dirty" high yield warhead for the Titan ICBM, only tested in reduced yield 9 megaton "clean" version). The typical hydrogen bomb in stockpile today is only about 100 kiloton to 300 kiloton as it had been demonstrated that yields higher than this really have little practical military value and actually produce less damage than lower total yield in multiple weapons detonated at multiple locations across the target area.
The "Tsar Bomba" was the biggest bomb ever detonated, at 50 megatons. The U.S has bombs ranging in yield of 0.01 Kilotons, to about 1 Megaton. The reason for 1 megaton, is that there is no real benefit of having them any bigger.
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)
The most powerful nuclear weapon detonated was the Tsar Bomb which was a 50 megaton thermo-nuclear bomb that was tested in October 30, 1961, in the Novaya Zemlya archipelago
The largest atomic bomb ever built, or detonated, was the Tsar Bomb (????-?????) RDS-220 code named "Ivan" by the Soviet Union. Originally built as a 100 MegaTon (100,000,000 ton) three stage Hydrogen bomb, it was changed to 50 MegaTon to limit fallout. Detonated on October 30th, 1961. Caveat: This information is based upon public information and releases, if there is a larger bomb it was never disclosed to the public in any fasion.
a megaton is bigger..
A solar flare
No one has actually tried this before, and no physics engine has ever managed to imitate effects of such great force, so therefore it is quite hard to answer this question.

Megaton Shotblast was created in 2001.
