d･wiの英語

語源

From Sanskrit द्वि (dvi, “two”).

接頭辞

dwi-

1. (chemistry, dated) A designation prefix for undiscovered chemical elements lying two periods under a known element in the periodic table. (For example, rhenium was called dwi-manganese before its discovery in 1925.)

使用する際の注意点

Current official IUPAC practice is to use a systematic element name based on the atomic number of the element as the provisional name, instead of being based on its position in the periodic table as these prefixes require.
