Morphology

atomic + number + 25

The phrase literally combines 'atomic' + 'number' + '25' to indicate the atomic-number property with the value 25, so learners who know the words can understand it refers to the element whose atomic number is 25. However, recognizing that this specific value corresponds to the element name 'manganese' requires encyclopedic knowledge of the periodic table beyond constituent meanings, so the transparency is partial.

Etymology

Atomic number 25 simply names the element manganese by its count of 25 tiny positive particles called 'protons'. So, when you see atomic number 25 it means 'manganese', the metal often added to steel to make it stronger.
