When selenium is added to glass, it is able to negate the color of other elements found in the glass and essentially decolorizes it. The aufbau principle is a method for determining the electronconfiguration of an element. Median response time is 34 minutes and may be longer for new subjects. Selenium is a photoconductor, which means it has the ability to change light energy into electrical energy. For example, the orbital diagram for the first 18 atoms are shown below. Can elements like gold be manufactured, if not why not ? Your email address will not be published. Exposure to an excess amount of selenium is known to be toxic and cause health problems. $Se_8 + 4Cl_2 \rightarrow 4Se_2Cl_{2(l)}$, $Se_8 + 4Br_2 \rightarrow 4Se_2Br_{2(l)}$. Find out about its chemical and physical properties, states, energy, electrons, oxidation and more. Selenium is used in the glass-making industry and also in electronics.

Answer to orbital diagram for selenium home / study / science / chemistry / chemistry questions and answers / Orbital Diagram For Selenium. The element can also be used in the production of alloys and is an additive to stainless steel. How many so 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4 Based off of the Greek word “selene,” meaning moon, Jons Berzelius decided to call the newly found element selenium. * if you're kind enough to put the electronic configuration...it will be appreciated :)). It shows how the various orbitals mustbe filled in correct sequence to. Selenium’s ability to change light energy into electrical energy increases as light intensity increases, Yes, selenium reacts with hydrogen and forms hydrogen selenide H. Selenium is important in the health of plants and animals, but is only safe in small amounts. 2 H2S(g) + 3 O2(g) 34Se: [Ar] 4s2 3d10 4p4 34Se: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4 by picture I assume you mean the orbital diagram. here is the electronic configuration . Some elements called metallo... A:  A metalloids are defined as those elements which have intermediate properties between those of meta... *Response times vary by subject and question complexity. Selenium also reacts with chlorine and bromine to form diselenium dichloride, $$Se_2Cl_2$$ and diselenium dibromide, $$Se_2Br_2$$. Get your answers by asking now. The electron configuration of selenium is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p4. Have questions or comments? The most thermodynamically stable allotrope of selenium is trigonal selenium and also appears as a gray. The binding energy of electrons in a metal is 180 kJ/mol . Selenium is a non-metal and can be compared chemically to its other non-metal counterparts found in Group 16: The Oxygen Family, such as sulfur and tellurium. Does selenium react with hydrogen? The discovery of selenium was an important finding, but at the same time seemingly accidental. Fellow scientist Martin Klaproth, discovered a contamination of sulfuric acid creating a red colored product which he believed to be due to the element tellurium. Describe selenium’s purpose as a trace element. Using a volumetric pipet, you take 50.00 mL of that solution and di... A: Given:M1 = 0.226 MV1 = 50.00 mL.V2 = 100.00 mLV3 = 10.0 mLV4 = 100 mL. Isotopes of an element are atoms that have the same atomic numbers but a different number of neutrons (different mass numbers) in their nuclei.

Besides its uses in the electronic industry, selenium is also popular in the glass-making industry. Too much selenium can be toxic and cause serious health problems. Discovery of the Elements, 7th edition. Part A Selenium forms hydrogen selenide, H2Se, a colorless flammable gas when reacted with hydrogen.
