| In an X-ray tube the beam of electrons is focused on a target of either tungsten or molybdenum which gives off X-rays. |
| Cupron is highly selective for copper ion in ammoniacal solution and for molybdenum in acid. |
| It was later identified that molybdenum was the most abundant trace element present in the soluble and insoluble extractions of the wood-ash. |
