Only two atomic bombs were used against man kind in war and neither of those were a thermonuclear or hydrogen bomb.
No, the bomb dropped on Hiroshima was an atomic bomb using uranium as the fissile material.
The fusion reaction in thermonuclear weapons (hydrogen bombs) is caused by the nuclear fusion of different isotopes of hydrogen (tritium and deuterium), hence the name.
Atom Bomb = Uranium H-Bomb = Hydrogen
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.
In general, a fusion bomb (hydrogen bomb) is more powerful than a fission (atomic) bomb. Fusion bombs use an atomic bomb to begin the fusion reaction.
A hydrogen bomb was not dropped on Japan. It was dropped years later as a test and to determine how it acted in comparison to the plutonium and uranium bombs.
It was dropped by the United States by orders of President Truman over Hiroshima, Japan.

No, the bomb dropped on Hiroshima was an atomic bomb using uranium as the fissile material.
Tsar Bomba was a hydrogen bomb which was actually detonated and not dropped. The test was held on October 30,1961. Tsar Bomba was the most powerful nuclear weapon ever detonated.
The first successful hydrogen bomb was detonated (not launched or dropped--it was a 62-ton fixed structure) on November 1, 1952.
Harry S Truman.
President Truman.
That was President Truman.
No one was president of Japan. They had an emperor . Truman was US president.
The hydrogen bomb was not invented until the 1950's. The planes that dropped the first fission-type atomic bombs in World War II are the Enola Gay and Bockscar.
