Yes, the core of the fission primary stage and the rod shaped "sparkplug" running the length of the fusion secondary stage (and any additional fusion stages) are usually made of plutonium.
Uranium plutonium and hydrogen
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
The Trinity bomb contained plutonium.
Uranium, Plutonium, Hydrogen, Lithium (depending on the specific bomb design)
Plutonium
No.
Uranium plutonium and hydrogen
A uranium bomb is an atomic bomb fueled by uranium-235A plutonium bomb is an atomic bomb fueled by plutonium-239A composite bomb is an atomic bomb fueled by both uranium-235 and plutonium-239A wet bomb is a hydrogen bomb fueled by liquefied deuterium/tritiumA dry bomb is a hydrogen bomb fueled by solid lithium deuteride
No, in terms of destruction the hydrogen bomb is the strongest, but if you mean killing the plutonium bomb is the one that does the most killing.
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.
Plutonium
plutonium + weapon
Yes, a bomb with plutonium.
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
Hydrogen bomb gets some of its energy from fusion, uranium or plutonium bomb gets all of it from fission. Either can be more powerful, depending on the design. The most powerful bombs built have all been hydrogen bombs.
The Trinity bomb contained plutonium.
