Understanding the definitions of lonization energy and electron a following data for iron: atomic
mass 55.845 electronegativity 1.83 electron affinity 15.7 ionization energy 762.5 heat of fusion
13.8 mol kJ mol mol kJ mol You may find additional useful data in the ALEKS Data tab. Does
the following reaction absorb or release energy? o release absorb Can't be decided with the data
given. yes (1) Fe (e) e Fe ) 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): release absorb Does the following
reaction absorb or release energy? (a) Fe (e)) Can't be decided with the data given. Is it possible
to calculate the amount of energy absorbedyes or released by reaction (2) using only the data
above? amount of energy absorbed or released by reaction (2): Explanation Check
Solution
the amount of enery spent or released when add an electron is called electron affinity
1) (Fe+2 )In the first case up coming electron entered in d subshell (d6) so it releases the energy.
That is may or may not 15.7 kj /mole
2) (Fe+ )In the second case up coming electron entered in s subshell (s1, it is half filled ) so here
the energy is required
