by whom was the first element mentioned discovered?
British mineralogist William Gregor.
Group 4 element
British mineralogist William Gregor first identified titanium in ilmenite sand beside a stream in Cornwall, Great Britain in the year 1791. After analyzing the sand, he determined the weakly magnetic sand to contain iron oxide and a metal oxide that he could not identify. During that same year, mineralogist Franz Joseph Muller produced the same metal oxide and could not identify it. In 1795, chemist Martin Heinrich Klaproth independently rediscovered the metal oxide in rutile from the Hungarian village Boinik. He identified the oxide containing a new element and named it for the Titans of Greek mythology.
