Metals have been an inseparable component of major civilizations since centuries. Although metals were utilized since time unknown, researchers put considerable efforts in giving them appropriate names and defining their different properties and characteristics. This nomenclature process helped in arranging these metals in a well-organized fashion, known as the periodic table. In this periodic table, Thallium metal is also represented by the symbol Tl. This atomic symbol of Thallium is useful in indicating the position of metal Tl in the periodic table. If you are curious-headed or a science-geek, the common questions about metals are What is Thallium? What are its physical, chemical, mechanical, electrical and thermal properties? Find all the relevant facts about Tl metals in the following sections.
Periodic Table of Thallium
Periodic table of Thallium comments over its position in the periodic table, on the basis of parameters like group number, period row, atomic number and orbital block. The metals which have electrons falling in the same sub-shell are grouped under the same block corresponding to its respective orbital. Thallium metal belongs to Post Transition Metals category of the periodic table. Metals down a group have same valency while metals across a period have the same number of shells. Its group number (column number) is 13, whereas its period number is 6. It is placed under p block of the periodic table & is one of the prominent p block elements.
