Morphology

atom + bomb

The compound combines 'atom' (the smallest unit of matter) and 'bomb' (an explosive device), so a learner who knows both words can reasonably infer it is a bomb that uses atoms or atomic reactions. The specific technical detail (nuclear fission/fusion) may be beyond a B1 learner, but the core meaning 'a bomb based on atoms' is transparently derivable and is cross-linguistically similar.

Etymology

Atom bomb comes from the idea of breaking the tiny atom, which people long thought could not be broken, so to 'split' an atom was imagined to let out huge energy like a very large bomb. That's why atom bomb means a weapon that releases massive energy and causes great destruction.
