Morphology

atomic + number + 100

The phrase is directly compositional: 'atomic' (relating to atoms) + 'number' (a numerical identifier) + '100' denotes the atomic-number label 100, i.e. the element with proton count 100 (fermium). This follows a regular noun-phrase naming pattern found across languages, so a B1 learner who knows the constituents can infer the meaning.

Etymology

Atomic number 100 names the element that sits in the 100th box of the periodic table, and scientists called that element fermium after the physicist Enrico Fermi. It was first found in the dust from an early nuclear test and is made by hitting plutonium with neutrons, so it is very radioactive.
