Which is worse Nuclear bomb or atomic bomb?

Answer 1

Basically the same thing. The 2 types of atomic/nuclear bombs are:

• Fission - works by breaking large heavy nuclei into smaller ones.
• Fusion - works by combining small light nuclei into bigger ones.

Fusion is commonly considered worse because it has no yield ceiling, just add more stages with more fuel to get any yield you want. Fission has a yield ceiling of about 1Mton, anything larger would melt as soon as it was armed and give almost no yield.

However practically all modern atomic/nuclear bombs are some mix of fission and fusion, depending on the bomb's requirements.

Answer 2

Both nuclear bombs and atomic bombs are extremely destructive weapons that release large amounts of energy through nuclear reactions. The terms are often used interchangeably, but typically an atomic bomb refers to a fission-based bomb, while a nuclear bomb can also include fusion-based bombs. Both can cause massive devastation and loss of life, with long-lasting environmental and health consequences. Ultimately, both types of bombs pose a significant threat to humanity and should be avoided at all costs.
