Question

calculate the Zeff for last electron of K+ion​

Answer 1

For the effective nuclear charge, you just find the amount of protons in potassium and then subtract it by the number of inner electrons. For potassium, the amount of protons is 19 (atomic number) and subtract that by 10, which is the amount of inner electrons.
