Morphology

atomic + number + eighty-four

The phrase is compositionally transparent: 'atomic' (relating to atoms) + 'number' + 'eighty-four' directly denotes the atomic identifier that picks out the element with that proton count. While it is a technical/scientific term, its meaning follows predictable compounding patterns (and similar constructions exist cross-linguistically), so a learner who knows the parts can infer it refers to the element with atomic number 84 (polonium).

Etymology

Atomic number 84 comes from how scientists count the small parts inside an atom: the element with 84 of those parts is called 'polonium'. Marie Curie named 'polonium' after her homeland, so today atomic number 84 simply means the radioactive metal 'polonium'.
