Shielding effect and Zeff Flashcards
1
Q
Why do valence electrons experience less attraction to the nucleus than do core electrons?
A
Because of the repulsion of the core electrons
2
Q
What is Z?
A
Total nuclear charge/ atomic number/ number of protons
3
Q
What is the effective nuclear charge (Zeff)?
A
The amount of attraction exerted on valence electrons by the nucleus
4
Q
Equation for Zeff
A
Z-S
#protons (Z) - # core electrons (S)
5
Q
