Chemical elements that have been mistakenly "discovered". Further investigation showed that their discovery was either mistaken, that they have been mistaken from an already-known element, or mixture of two elements, or that they indicated a failing in theory where a new element had been assumed rather than some previously unknown behaviour.[i]
Not discovered, but hypothesised to explain discrepancies within the
iron group elements for an early periodic table ordered by mass. The concept of
atomic number clarified the situation without requiring the invention of a new element.
