Ok but how many valence electrons does an atom of Tellurium have? It means it has a negative 2 charge, which means it has gained two electrons. For the neutrons, you're missing a number - the mass number. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Tellurium Properties. The number of electrons in each of Tellurium's shells is 2, 8, 18, 18, 6 and its electron configuration is [Kr] 4d 10 5s 2 5p 4.In its elemental form tellurium's CAS number is 13494-80-9. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. Atomic Mass 127,6 Learn more about the atomic mass. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. The atomic number of tellurium is 52, so there are 52 protons. Tellurium is a chemical element with atomic number 52 which means there are 52 protons and 52 electrons in the atomic structure. Tellurium is a Block P, Group 16, Period 5 element. Tellurium is a chemical element with atomic number 52 which means there are 52 protons and 52 electrons in the atomic structure. Characteristics of tellurium. Its main features are as follows: Its atomic number is 52. The atomic number increases from left to right. Notes on the properties of Tellurium: Specific Heat: Value given for solid phase. Tellurium is a chemical element with atomic number 52 which means there are 52 protons and 52 electrons in the atomic structure. Tellurium-128 does indeed have 76 neutrons, but it isn’t the commonest isotope. the number of isotope depends on the isotope. In the case of Tellurium the valence electrons is 2,4,6. Possible oxidation states are +4,6/-2. Name: Tellurium Symbol: Te Atomic Number: 52 Atomic Mass: 127.6 amu Number of Protons/Electrons: 52 Number of Neutrons: 76 Date of Discovery: 1782 Discoverer: Franz Muller von Reichenstein Uses: coloring of glass and ceramics, thermoelectric devices Classification: Metalloid Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The chemical symbol for Tellurium is Te. Electron Configuration and Oxidation States of Tellurium. The chemical symbol for Tellurium is Te . Up to date, curated data provided by Mathematica 's ElementData function from Wolfram Research, Inc. The atomic number of tellurium is 52. The chemical symbol for Tellurium is Te. Now let's check the facts about Tellurium... Tellurium Overview Tellurium Valence Electrons 2,4,6 Atomic Number 52 Learn more about the atomic number. The charge is 2-, so there are two more electrons than protons, 54. Has a melting point of 450° C. Its boiling point is 988° C. It has a density of 6.24 g.cm-3. Te-128 has 76 neutrons. So there are 52 protons and 52 electrons. Tellurium has 33 isotopes whose half-lives are known, with mass numbers 106 to 138. The atomic mass of tellurium is 127.6 u. The commonest isotope is tellurium-130 with 78 neutrons. The atomic symbol with which we find it in the periodic table of the elements is the Te. Tellurium is chemically related to selenium and sulfur. Electron configuration of Tellurium is [Kr] 4d10 5s2 5p4. The electron configuration of Tellurium can be expressed as {eq}\rm 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^{10} 5p^4 {/eq}.
