Description

Thallium is a chemical element; it has symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly developed method of flame spectroscopy, in which thallium produces a notable green spectral line. Thallium, from Greek θαλλός, thallós, meaning "green shoot" or "twig", was named by Crookes. It was isolated by both Lamy and Crookes in 1862; Lamy by electrolysis, and Crookes by precipitation and melting of the resultant powder. Crookes exhibited it as a powder precipitated by zinc at the international exhibition, which opened on 1 May that year.

थैलियम (Thallium) एक रासायनिक तत्त्व है। यह आवर्त सारणी के तृतीय मुख्य समूह का अंतिम तत्व है। इसके दो स्थिर समस्थानिक प्राप्त हैं, जिनकी द्रव्यमान संख्याएँ २०३ एवं २०५ हैं। इसके अतिरिक्त इसके नौ अस्थिर समस्थानिक ज्ञात हैं। इनकी द्रव्यमान संख्याएँ १९९, २००, २०२, २०४, २०६, २०७, २०८, २०९ और २१० हैं। इनमें कुछ रेडियधर्मी अयस्कों में मिलते हैं और कुछ कृत्रिम साधनों द्वारा उपलब्ध हैं। इस तत्व की खोज अंग्रेज वैज्ञानिक विलियम क्रुक्स ने १८६१ ईo में एक विशेष सेलेनियम युक्त पायराइट में वर्णक्रममापी (spectroscopic) उपकरण द्वारा की। उन्होंने भूर्जित (roasted) अयस्क की धूल के वर्णक्रममापी निरीक्षण में एक हल्के हरे रंग की रेखा देखी, जिसके कारण इस तत्व का नाम थैलियम रखा। इस तत्व को लैमी (Lamy) ने सर्वप्रथम पृथक् कर इसके गुणधर्म का निरीक्षण किया।
