Morphology
atomic + number + thirty-nine
The phrase is compositionally built from 'atomic' + 'number' + 'thirty-nine', so a learner who knows the words can infer it refers to the atom/element identified by the numeral 39 (i.e., an index in the periodic table). However, identifying that atomic number 39 corresponds specifically to yttrium requires subject-specific knowledge (periodic table mapping), so the meaning is partly transparent but not fully predictable from the constituents alone.
Etymology
Atomic number 39 is like an address in a long row of elements, like houses on a street: atomic points to an atom and number 39 is the house number for the element 'yttrium'. That's why atomic number 39 means the metal 'yttrium'.
