We elaborate the uses of Thallium and atomic properties with characteristics. Thallium is a silvery-white chemical element with atomic number 81. Its symbol is Tl and it belongs to the group of metals in the p block and its usual state in nature is solid. Thallium is located at position 81 on the periodic table.
On this page you can discover the chemical properties of thallium and information about thallium and other elements of the periodic table such as indium, ununtrium, mercury or lead. You will also learn what thallium is for and you will know its uses through its properties associated with thallium such as its atomic number or the usual state in which thallium can be found.
You will be able to see qualities of thallium such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in the thallium atoms and other properties.
For some elements, part of this information is unknown. In these cases we show the properties attributed to them.
Thallium belongs to the group of metallic elements known as the p-block metals that are located next to the metalloids or semimetals in the periodic table. These types of elements tend to be soft and have low melting points, properties that can also be attributed to thallium, since it is part of this group of elements.
The state of thallium in its natural form is solid. Thallium is a silvery-white chemical element and belongs to the group of the p-block metals. The atomic number of thallium is 81. The chemical symbol for thallium is Tl. Thallium’s melting point is 577 degrees Kelvin or 304.85 degrees Celsius, or degrees Celsius. The boiling point of thallium is 1746 degrees Kelvin or 1473.85 degrees Celsius or degrees Celsius.
Atomic properties of thallium
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. Regarding the position where to find thallium within the periodic table of elements, thallium is found in group 13 and period 6. Thallium has an atomic mass of 204.3833 u.
The electron configuration of thallium is [Xe] 4f14 5d10 6s2 6p1. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element.
