Taisgealadh

[deasaich | deasaich an tùs]

Ann an 1875 lorg Paul-Émile Lecoq de Boisbaudran dà loidhne phurpaidh anns a speactram na sfailerit agus bharailich e gun robh iad à eileamaid ùr, gailium. Anns an aon bliadhna fhuair e meatailt na ghailium nuair a chuir e sruth dealain tro eadar-sgaoileadh na ghailium haidreogsaid.

Tha an t-ainm a' dol às an t-ainm Laidinneach Gallia, An Fhraing, ach tha Laideann gallus cuideachd a' ciallachadh "coileach", mar "Lecoq" ann am Fraingis.

Tha gailium ga cleachdadh mar gailium arsenagaid no gailium naitriaid ann an leth-ghiùlanairean.
