Question

answer each question for Mn (element #25).

(0.5 points) 2. (a) Write out the equation that corresponds to the 8th ionization. Include phases. You do not need to include the ionization energy.

 

(0.5 points) 2. (b) Write out the equation that corresponds to the 5th electron affinity process. Include phases. You do not need to include the electron affinity energy.

 

(3 points) 2. (c) Use a Noble gas core to represent the core electrons and an orbital diagram to represent the electron configuration of the valence electrons for the following. Clearly label your orbital diagram. (Hint: Follow the formatting from Example 7.11 in your textbook.)

 

i. A neutral atom of your element

ii.The product ion from (a)

iii.The product ion from (b)

 

(0.75 points) 2. (d) State if each of the species in (c) is paramagnetic or diamagnetic.

 

(1.25 points) 2. (e) Rank the species in (c) from smallest to largest radii. Write no more than two sentences to explain your ranking. Use the term "Zeff" at least once in your explanation. Please print neatly.

Answer 1

a). Mn⁷⁺(g) ==> Mn⁸⁺(g) + e- ... IE₈

b). Mn^4-(g) + e- ==> Mn^5- ... EA₅

c). I don't have your example 7.11 and don't know your element

The product ion from (a) is Mn⁸⁺.

[Ar]4s²3d¹⁰4p³ ^v ^v^v^v^v^v ^^^

The product ion from (b) is Mn^5-.

[Ar]4s² ^v

d). Mn⁸⁺ is paramagnetic

Mn^5- is diamagnetic

e). don't have your element or example 7.11
