One of the mysteries of the English language finally explained.
The name formerly proposed by the American Chemical Society for the chemical element of atomic number 105 (dubnium), and by IUPAC for element 108 (hassium).
- ‘They proposed the name hahnium - after the late German scientist Otto Hahn - and symbol Ha.’
- ‘The heaviest element whose discovery has been previously confirmed is element 105, hahnium.’
- ‘Some scientists still use the earlier name of hahnium because it had been used for about 25 years.’
- ‘Investigation of the chemical properties of the actinides was followed more recently by chemical studies of the first three transactinides - rutherfordium, hahnium, and seaborgium.’
- ‘The name ‘bohrium ‘was recommended for 107 (instead of GSI's choice of nielsbohrium), and ‘hahnium ‘for 108 (instead of GSI's choice of hassium).’’
1970s: named in honour of Otto Hahn (see Hahn, Otto).
