Selenide IonThallium Selenide (TlSe) is a crystal grown product generally immediately available in most volumes. Technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Thallium (Tl) atomic and molecular weight, atomic number and elemental symbolThallium (atomic symbol: Tl, atomic number: 81) is a Block P, Group 13, Period 6 element with an atomic weight of 204.38.Thallium Bohr Model The number of electrons in each of thallium's shells is 2, 8, 18, 32, 18, 3 and its electron configuration is [Xe] 4f14 5d10 6s2 6p1. The thallium atom has a radius of 170 pm and a Van der Waals radius of 196 pm. Thallium was discovered by Sir William Crookes in 1861 and first isolated by Claude-Auguste Lamy in 1862. Thallium is a post-transition metal that is not found free in nature. Thallium is primarily used for its electrical conductivity as thallium sulfide, which changes with exposure to infrared light. This ability makes the compound useful in photocells.Elemental Thallium Thallium bromide-iodide crystals have been used as infrared optical materials. Thallium has also been used with sulfur, selenium or arsenic to produce low melting glasses which become fluid between 125 and 150 °C, while thallium oxide has been used to produce glasses with a high index of refraction, and is also used in the manufacture of photo cells. Its name is drived from the Greek word thallos, which means twig or green shoot.

Selenium Bohr ModelSelenide(Se) atomic and molecular weight, atomic number and elemental symbolSelenium (atomic symbol: Se, atomic number: 34) is a Block P, Group 16, Period 4 element with an atomic radius of 78.96. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d10 4s2 4p4. The selenium atom has a radius of 120 pm and a Van der Waals radius of 190 pm. Selenium is a non-metal with several allotropes: a black, vitreous form with an irregular crystal structure; three red-colored forms with monoclinic crystal structures; and a gray form with a hexagonal crystal structure, the most stable and dense form of the element. Elemental Selenium One of the mose common uses for selenium is in glass production; the red tint that it lends to glass neutralizes green or yellow tints from impurities in the glass materials. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. The origin of the name Selenium comes from the Greek word "Selênê," meaning moon.
