Question

Calculate the effective nuclear charge experience by the 4s electron of k atom

Answer 1

Answer:

However, all electrons in the same orbit have the same effective nuclear charge. What is screening constant of the 4s electron of potassium? Atomic number = 19. Screening effect of 4s = 0×0.35+8×0.85+10×1 = 0+6.8+10= 16.8.
