Consider a magnesium (Mg) atom that could have an electronic configuration of either [Ne]3s2 or [Ne]3s13p1.  Discuss the following: a)  Give one argument for why the [Ne]3s2 configuration might be more stable. b)  Give one argument for why the [Ne]3s13p1 configuration might be more stable. c)  Which configuration does Mg actually adopt and why?

Group the electronic configurations of neutral elements in sets according to those you would expect to show similar chemical properties. 15²2s²2p²38²3p³ 1s²2s²2p³: Set A 1s²2s²2p 3s²3p: 15²25²2p% 15² 3400 4p/5 1s²2s22p 3s23p648²3d¹04p6: 1s²2s²2p638²3p³: Answer Bank Determine the chemical symbols for the neutral elements corresponding to the electronic configurations. Use proper formatting; letter case matters. 1s²2s²2p³ 35²3p² 13²23²2p³ Set B

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 therefore, what will be the electron affinity in kJ/mol of bromine from the following equations?. Explain the development.
