Thallium silih tunggil datu kimia antuk simbol Tl miwah wilangan atom 81. Punika logam pasca transisi mawarna klau sané nénten katemuin bébas ring palemahan. Ri kala kaisolasi, talium marupa sakadi timah, menawi magentos ri kala keni udara. Chemists William Crookes miwah Claude-Auguste Lamy nemuin talium sacara mandiri ring warsa 1861, ring résidu produksi asam sulfat. Makakalih nganggén metode spéktroskopi ngendih sané anyar kakembangang, ring dija thallium ngasilang garis spéktrum ijo sané kasub. Thallium, saking Basa Yunani θαλλός, thallós, sukman ipun "muncuk ijo" utawi "carang", kaaranin olih Crookes. Punika kaisolasi olih Lamy miwah Crookes warsa 1862; Lamy nganggéb éléktrolisis, miwah Crookes nganggén pangendepan miwah paleburan sané ngasilang bubuk. Crookes nyingkang dados bubuk sané kaendepang olih séng ring pameran Internasional, sané kawéntenang ring 1 Méi warsa punika.^[4]
