Morphology

atomic + bomb

The meaning is directly compositional: 'atomic' (relating to atoms or nuclear energy) combined with 'bomb' (an explosive device) yields a bomb that uses atomic/nuclear reactions. This noun–noun compound follows regular, cross-linguistically common formation patterns, so a B1 learner who knows both constituents can infer the meaning.

Etymology

Atomic bomb gets its name from the atom, the tiny part of matter. When scientists learned to split atoms, a bomb could release a huge amount of energy, so the name came to mean a weapon with 'very great power to destroy'.
