Morphology
atomic + number + thirty-seven
The phrase is fully compositional: 'atomic' (relating to atoms) + 'number' + 'thirty-seven' yields the clear concept 'the element whose atomic number is 37'. Although somewhat technical, the meaning (the element identified by atomic number 37, i.e. rubidium) can be directly derived from the constituents and is cross-linguistically similar, so a B1 learner who knows the words and the basic idea of atomic numbering would understand it.
Etymology
Atomic number 37 comes from the ordered list of chemical elements where each element has its own number. In that list, '37' is the place for rubidium, so saying atomic number 37 means 'rubidium'.
