Question

Date calculate Zeff of last election in cl, Na.
​

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
