Morphology
The phrase is compositionally clear: 'atomic' + 'number' + '103' indicates an atomic identifier — i.e. the element with proton/atomic number 103. However, mapping that identifier to the specific element name (lawrencium) is encyclopedic chemistry knowledge and not derivable from the constituent words alone, so a B1 learner who only knows the words would not necessarily know the precise referent.
Etymology
Atomic number 103 is the label scientists use for the element 'lawrencium'. The phrase comes from the idea of atomic number meaning the count of protons in an atom, so 103 tells you it has 103 protons and that number names that specific element.
