Question

O ELECTRONIC STRUCTURE Understanding the definitions of ionization energy and electron... Consider the following data for manganese: atomic mass 54.9388 mol electronegativity electron affinity 0 mo ionization energy 717.3 mol heat of fusion kJ 13.2 mol You may find additional useful data in the ALEKS Data tab. Does the following reaction absorb or release energy? release absorb (1) Mn (g) + e - Mn(8) Can't be decided with the data given. yes Is it possible to calculate the amount of energy absorbed or released by reaction (1) using only the data above? no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (1): J/mol Does the following reaction absorb or release energy? release absorb Can't be decided with the data given. (2) Mn () → Mn(g) + e yes Is it possible to calculate the amount of energy absorbed or released by reaction (2) using only the data above? no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (2): J/mol

Answer 1

1.Absorb

As the Manganese ion has 0 electron affinity , it will be forced to take up the electron hence energy is to be given for accepting the electron so energy will be absorbed.

2.release

It will release energy because by losing one electron the Mn^- will turn into more stable half filled arrangement that is 3d⁵
