'S e meatailt talmhaidh alcaileach le feartan coltach ri na feartan sodium is potasium a tha ann.

Taisgealadh

Ann an 1808 rinn Humphry Davy magnesium fìor-ghlan nuair a chuir e sruth dealain tro mheasgachadh magnesium ogsaid agus mearcair ogsaid (HgO).

Cleachdadh

Tha ceimigear fàs-bheairteach a' cleachdadh magnesium ann an co-thàthaidhean Grignard. Tha co-thàthaidhean Grignard cuideachail airson ataman carbon a cheangal.
