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. Question Astatine is placed below iodine in group 7 . For example, chlorine can oxidise the bromide ions (in, for example, potassium bromide solution) to bromine: Cl 2 + 2Br - 2Cl - + Br 2. Out of the 4 ions, only F e X 2 + has a mild enough reducing power. Since this is not a superoxide or a peroxide, or any other case where the oxidation state of oxygen is not −2 according to this, so the oxidation state of oxygen should be −2. Bromine -7 59 Liquid Iodine +114 184 Solid Trends in electronegativity Electronegativity is the relative tendency of an atom in a molecule to attract electrons in a covalent bond to itself.
