Morphology
The phrase is compositionally built from 'atomic' (relating to atoms), 'number' and the numeral '95', so a learner can infer it refers to the atomic-number identifier for a specific chemical element. However, mapping that identifier to the specific element name 'americium' requires domain knowledge of the periodic table beyond a B1 learner's likely knowledge, so the full referent is not predictable from the parts alone.
Etymology
Atomic number 95 tells you how many protons an atom has: an atom with 95 protons is the element 'Americium', which was named after 'America' when it was discovered. So atomic number 95 is the way scientists refer to the chemical element 'Americium'.
