What is the family of aluminum?
Boron Family
Boron Family This group includes the elements boron, aluminum, gallium, indium, and thallium. All five have three electrons in their outer energy level. Only one member of this family is a metalloid — boron.
What is the name of the family of the elements in group 16?
The oxygen family
The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium. These can be found in nature in both free and combined states.
What is the name of group 16 elements?
oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
What family is thallium in on the periodic table?
Thallium is a member of the aluminum family, Group 13 (IIIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Thallium is also a member of the heavy metals, along with gold, platinum, and lead.
What is thallium (Tl)?
Thallium (Tl) with an atomic number of 81 is found in the periodic table with the symbol. Thallium is not freely found in nature. It is a soft grey post-transition metal. There are around eighty-one electrons present in the atom of thallium with an electronic configuration of [Xe] 4f 1 4 5d 1 0 6s 2 6p 1. This element can be generated artificially.
Where is thallium found in nature?
Thallium is found in several ores. One of these is pyrites, which is used to produce sulfuric acid. Some thallium is obtained from pyrites, but it is mainly obtained as a by-product of copper, zinc and lead refining. Thallium is also present in manganese nodules found on the ocean floor.
Who discovered the element thallium?
The discoverer of thallium was British physicist Sir William Crookes (1832-1919). Interestingly, thallium was discovered at almost the same time by French chemist Claude-Auguste Lamy (1820-78). Lamy discovered thallium the “old fashioned way,” by separating one of its minerals in the laboratory.
