: elemento 107

Before receiving an official name, element 107 was simply identified by its atomic number.

Examples

Morphology

element + 107

The phrase is fully compositional: combining 'element' (a chemical substance) with the number '107' straightforwardly denotes the chemical element whose atomic number is 107. A B1 learner who knows the word 'element' and basic numbers can infer this meaning (even if they may not know the name 'bohrium' or technical details).

Etymology

Element 107 comes from how scientists label new atoms: they use the word element plus the number 107 as a simple, temporary name until a proper name is chosen. So element 107 means the man-made atom with the number 107, later given the official name 'bohrium'.
