Question

Using the equation Zeff = Z - S and assuming that core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant, S, calculate Zeff for the 2p electrons in F^- and Na^+
Repeat this calculation using Slater's rules to extimate the screening constant,S.

Answer 1

7,9

Answer 2

This seems to be just an exercise in subtraction; what do you not understand about it.

Answer 3

Using slater's rules:
S = 4.15
Zeff F^- = 4.85
Zeff Na^+ = 6.85

*these answers are in e^-(electrons)*

Answer 4

Chris is right!

THANKS SO MUCH MAN!!!

Answer 5

Using the equation Zeff=Z−S and assuming that core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant, S, calculate Zeff for the 2p electrons in both ions.
Express your answers as integers. Enter your answers numerically separated by a comma.
Zeff F−, Zeff Na+ = 7,9 e−
