There are two ions, k+ and cl-. find the zeff for each if the valence electrons contribute 0, and the core electrons contribute. now calculate the zeff using slater's rules.

2. For CI-, Zeff = 17 - (0.35(7) + 0.85(8) +2) = 5.75

I am hoping that these answers have satisfied your queries and it will be able to help you.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

it is the most commonly accepted one
