Fluorine has only -1 oxidation state in compounds. does not show Alkene undergoes an addition reaction. Fluorine has only -1 oxidation state due to the absence of vacant n-’d’ orbitals. And thus we have zerovalent bromine. Reason Fluorine has maximum electronegativity and electron-affinity. close. - Quora Answer (1 of 6): Actually, bromine can. Other halogens have d orbitals and therefore, can expand their octets and show + 1, + 3, … why chlorine and bromine form+4and+6 oxidation state but not … 80% A 70% B AS Level Chemistry 60% C 2008 - 2009 50% D 40% E Below U 2.4, 2.5 and 2.6 Assessed Homework % Redox Reactions Group 7, the Halogens Group 2, the Alkaline Earth Metals 56 1. However, elements such as chlorine, bromine, and iodine also show +1, +3, +5 and +7 state. Out of the 4 ions, only F e X 2 + has a mild enough reducing power. In sodium compounds, sodium only forms +1 oxidation number. Year 12 - A-Level Chemistry Statement -1 Fluorine does not show oxidation number greater than zero. Bromine is a deep-red, oily liquid with a sharp smell. Evaluate vital signs including pulse and respiratory rate, and note any trauma. All efforts have been made to make the chapter fully accessible by providing headings, - describing figures and tables. Bromine is a chemical element with the symbol Br and atomic number 35. Give a use for barium sulfate in medicine and explain why this use is possible, given that solutions containing barium ions are poisonous. What is the … Biology . So I think the question changes to why are the elements down the group more able to form oxygen compounds with decreasing oxidation state of oxygen, and that is due to the size of the metal atoms; the larger the metal atom, the higher number of oxygen atom containing species it can (stably) accommodate around it.
