Morphology

atomic + number + 85

The meaning is directly composed from 'atomic' (relating to atoms) + 'number' + the numeral 85, so it refers to the element identified by atomic number 85. This is a technical but fully compositional label (cross-linguistically regular), so a B1 learner who knows the parts can infer it denotes the element astatine even if they lack deeper chemical detail.

Etymology

Atomic number 85 tells us which element has 85 protons in the center of its atoms. So it points to the element 'astatine', which is very rare and unstable.
