Thallium | Chemical Element, Poisonous Metal, Uses & Properties

Thallium is typical of the Group 13 elements in having an s 2 p 1 outer electron configuration. Promoting an electron from an s to a p orbital allows the element to be three or four covalent. With thallium, however, the energy required for s → p promotion is high relative to the Tl–X covalent bond energy that is regained on formation of TlX 3; hence, a …
