Yes, it is!
No they are the same thing.
No. Atomic bombs use fission, hydrogen bombs use fusion (and are more powerful)
No, an atomic bomb uses fission, but a nuclear or thermonuclear bomb combines fission and nuclear fusion. Therefore, a nuke is more powerful than an atom bomb.
They are the same thing using different names.
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
No. A nuclear missile is a rocket of some kind with an atomic/nuclear bomb as its warhead.
They are both the same thing.
About the same thing as happened to the people.
Actually, niether because they are both the same thing.
No, Atomic number is the number of protons in an atom. Atomic mass is the number of protons plus the number of neutrons.
The inside of an atom bomb is not the same as the inside of a baseball, but the fissile material (enriched uranium/plutonium) contained in an atom bomb could be about the same size as a baseball. The material is surrounded by shaped explosives, detonators, control circuits and a suitable casing. If a baseball was the same as an atomic bomb, nobody would play the game due to an unacceptable risk of vapourisation or radiation poisoning.
This question makes no sense as an atomic bomb is a nuclear bomb and vice versa. They are the same thing.
