- Bromine is used in the manufacture of disinfectant products, it has a very strong oxidizing character, due to the great electronic affinity it presents. Based on this, what will be the electron affinity in kJ/mol bromine from the following equations?arrow_forwardThe first ionization energy of the oxygen molecule is the energyrequired for the following process:O2(g)---->O2 +(g) + e-The energy needed for this process is 1175 kJ/mol, very similarto the first ionization energy of Xe. Would you expect O2 to reactwith F2? If so, suggest a product or products of this reaction.arrow_forwardWhat is the valence electron configu.ration for Group SA (lS) elements?Metallic character increases when going down a group. Give some examples illustrating how Bi and Sbhave metallic characteristics not associated with N, P,and As. Elemental nitrogen exists as N2 whereas in the gas phase the elements phosphorus, arsenic, and antimony consist of P4' As4, and Sb4 molecules, respectively.Give a possible reason for" this difference between N2 and the other Group SA (lS) elements. White phosphorus is much more reactive than black or red phosphorus. Explain.arrow_forward
