systematic element name
Noun

systematic element name (plural systematic element names)

  1. (chemistry) A systematic name for an element, derived from the digits of its atomic number to which the suffix -(i)um is appended; normally only used for transuranic elements before or for a short period after they have been created, after which they will be given a non-systematic name.
    Before the IUPAC named the element with atomic number 106 “seaborgium” in honour of Glenn Seaborg, it was referred to by the systematic element name unnilhexium.
