Morphology

atomic + number + 104

The phrase is a straightforward composition: 'atomic' (relating to atoms) + 'number' + the numeral '104' denotes the atom/element assigned number 104. This is a conventional, cross-linguistic scientific naming pattern so a learner who knows the constituents can infer it refers to the chemical element with proton/atomic number 104 (even if they may not know the proper name rutherfordium).

Etymology

Atomic number 104 names the element rutherfordium and literally shows how many protons its atoms have: atomic number means 'the number of protons' and 104 is that count. Because this element is made in labs and disappears quickly, using the number '104' gives scientists a clear, simple name.
