previous l 10 of 27/ ne Part B Use Equation 7.1 and assuming that core electrons contribute 1.00 and valence electrons contribute nothing to the screening constant, S, calculate Zft for these two ions Express your answers as integers.

Equation of Zeff is
Zeff = Z - s, where z is the number of protons in the nucleus (atomic number ) and S the inner shell electrons
Chlorine has an atomic number of 17, the electron configuration of chlorine is 1s22s22p63s23p6 , you have to count the inner shell electrons , these are the electrons that occupy complete orbitals, 1 and 2 (1s22s22p6 ) if you count them you will get 10 core electrons
Zeff = 17 - 10 = 7
for pottasium is similar , it has atomic number of 19 and 1s22s22p63s23p6 (this is for K+)just count the electrons from 1 and 2 level to get a number of 10 electrons
Zef = 19 - 10 = + 9
