Question

Find the value of 'a' in equation '(a + 0.30) + 0.65 (n–1)' which represents the value of effective nuclear charge experienced by last electron of 2nd period element.(where n is number of electrons in 2nd shell​

Answer 1

Answer:

Z = 17. Z∗=Z−S = 17 - [(0.35 × No. of other electrons in nth shell)] + (0.85 × No. of electrons in (n - 1)th shell) + (1.00 × total number of electrons in the inner shells) =17−[(0.35×6)+(0.85×8)+(1×2)] =17−10.9=6.1
