[29], Tellurites can be leached from the mixture with water and are normally present as hydrotellurites HTeO3− in solution. In concentrations of 25 mg/m3, tellurium is immediately dangerous to life and health. In 1798, it was named by Martin Heinrich Klaproth, who had earlier isolated it from the mineral calaverite. It burns in air with a greenish-blue flame and forms tellurium dioxide (TeO 2).Tellurium is a semiconductor material and is slightly photosensitive. 1. a member of the same family as oxygen whose most stable ion contains 54 electrons.

It is a component of dusts from blast furnace refining of lead. It has a density of 6.24 g.cm-3. Tags: Question 3 . The dihalides have not been obtained in pure form,[36]:274 although they are known decomposition products of the tetrahalides in organic solvents, and the derived tetrahalotellurates are well-characterized: where X is Cl, Br, or I. To use electron affinities properly, it is essential to keep track of sign. Tellurous acid forms tellurite salts containing the anion TeO2−3. Determine the charge of each of the following ions. Next, start filling the orbitals. Because atoms have the same number of protons and electrons. The mass number in amu is (do not include units in your answer): a. The potassium atom has one electron removed to for the corresponding ion, while calcium loses two electrons. Tags: Report an issue. 1. tungsten ion with 68 electrons = 6+. The rarity of tellurium on Earth is thought to be caused by conditions during preaccretional sorting in the solar nebula, when the stable form of certain elements, in the absence of oxygen and water, was controlled by the reductive power of free hydrogen. Tellurium is a rare, silvery-white, brittle, lustrous metalloid. When crystalline, tellurium is silvery-white with a metallic luster. Because it now only has 54 electrons, that means it LOST 2 electrons to yield that +2 charge. [22] The following year, he reported that this was erroneous and that the ore contained mostly gold and an unknown metal very similar to antimony. Tellurium is added to lead to improve its durability, strenght and resistence to corrosion. Identify the element. The element is: a.    Metalloids For example, +2 or -1. barium ion with 54 electrons Enter a signed integer. Even though the metabolic pathways of tellurium are not known, it is generally assumed that they resemble those of the more extensively studied selenium because the final methylated metabolic products of the two elements are similar. [58] Bismuth telluride (Bi2Te3) and lead telluride are working elements of thermoelectric devices. This is caused by the body converting tellurium from any oxidation state to dimethyl telluride, (CH3)2Te. The answer is e) Sr^(2+) For an ion to be isoelectronic with an atom (or with another ion), it must have the same number of electrons surrounding its nucleus. 8.

An atom of Tellurium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Tellurium. When tellurium is treated with concentrated sulfuric acid, the result is a red solution of the Zintl ion, Te2+4. Tellurium has the atomic number 52, meaning the neutral atom has 52 electrons. [41], Tellurium dioxide is formed by heating tellurium in air, where it burns with a blue flame. The chemical symbol for Tellurium is Te. Telluraethers (R–Te–R) are more stable, as are telluroxides. An isotope has 82 protons, 126 neutrons, and 78 electrons. 54 electrons. In most cases, tellurium becomes an electron acceptor because taking two electrons from one atom is easier than giving six electrons to another. (Cesium??) The alkali metal family is group I and those elements lose one electron to become the X^+ ion. [44] Like H2Te, these species are unstable with respect to loss of hydrogen.  Links, Show Table With: [36]:281 Polynuclear anionic species also exist, such as the dark brown Te2I2−6,[36]:283 and the black Te4I2−14.

Atomic Mass of Tellurium Atomic mass of Tellurium is 127.6 u. [37] The square antiprismatic anion TeF2−8 is also attested. Tellurium is a group VIB metalloid like selenium, but its lower position in the periodic table suggests that it has considerably more metallic character than selenium. Nitrogen (#7) with 10 electrons has a -3 charge. It is brittle, so it can easily pulverized. Look for the oxygen family. It is a brittle and easily pulverized metalloid.

To determine: The element that is a member of same family as oxygen with a stable ion containing 54 e −. [79] Tellurium poisoning is particularly difficult to treat as many chelation agents used in the treatment of metal poisoning will increase the toxicity of tellurium. The hydrotellurites are converted into the insoluble tellurium dioxide while the selenites stay in solution. [46][47][48] Replacing some of the cadmium in CdTe with zinc, producing (Cd,Zn)Te, produces a solid-state X-ray detector, providing an alternative to single-use film badges. The energy released when an electron is added to the neutral atom and a negative ion is formed. It is mildly toxic. The −2 oxidation state is exhibited in binary compounds with many metals, such as zinc telluride, ZnTe, produced by heating tellurium with zinc. [28][45], Tellurium is used in cadmium telluride (CdTe) solar panels. Tellurium belongs to the oxygen family, also called the chalcogens. Therefore, a systematic voltammetric investigation using its polarographic behavior is required for a comprehensive understanding of Te reduction in alkaline media. Electron Affinity of Tellurium is 190.2 kJ/mol. When molten, t… The addition to steel and copper produces an alloy more machinable than otherwise. When an electron is added to a neutral atom, energy is released. 1. tungsten ion with 68 electrons = 6+ 2. tellurium ion with 54 electrons =2- 3. nitrogen ion with 10 electrons = 3- 4. barium ion with 54 electrons = 2+    Name (a) the ion with a 1+ charge, atomic number 55, and mass number 133 (b) the ion with 54 electrons, 53 protons, and 74 neutrons (c) the ion with atomic number 15, mass number 31, and a 3− charge (d) the ion with 24 electrons, 30 neutrons, and a 3+ charge Determine the charge of each ion.
