30
Q

Effective Nuclear charge

A

Zeff = Z-O

31
Q

Slaters rule

A

ns and np
Electrons within the same group shield 0.35
N-1 shield 0.85
N-2 or more shield 1
for nd and nf
within the group shield 0.35
lower shield 1

32
Q

how do you use electrons in zeff

A

z is the total number.
o will have one less because we are looking at it.

multiply the number of electrons in that level by slaters number do the same for the other level and subtract
