Morphology
atomic + number + forty-eight
The phrase is compositionally transparent in that a learner who knows 'atomic', 'number' and 'forty-eight' can infer it refers to the atomic-number label 48 (i.e. the element with that atomic number). However, identifying that atomic number 48 specifically names the element cadmium requires domain/encyclopedic chemistry knowledge beyond the constituent words, so the mapping to the lemma 'cadmium' is not fully predictable for a B1 learner.
Etymology
Atomic number 48 is a simple scientific label for the element 'cadmium'. The word atomic and the number tell how many tiny particles called 'protons' are inside the atom, and because cadmium atoms have 48 of these, atomic number 48 means 'cadmium'.
