What value is the closest estimate of Z_eff for a valence electron of the calcium atom? A) 20 B) 40 C) 2 D) 6 E) 1

Question

Quizplus · Accepted Answer

The effective nuclear charge (Z_eff) for a valence electron is calculated by subtracting the shielding effect of inner electrons from the actual nuclear charge. For calcium, with an atomic number of 20, the inner electrons shield the valence electrons significantly, resulting in a Z_eff close to 2.
