Question

Which of the following reactions would not produce an octet of electrons in the ion product?

a. Ca → Ca2+ + 2e-
b. B + 3e- → 83 S+ 2e-
c. s2 dCs → Cs

Answer 1

In order to achieve an octet of electrons in the ion product, S will gain two electrons to form S²- anion. Gaining three electrons to form S³- does not make it octet, and therefore, S³- is not likely to form.

Step-by-step explanation:

(a) S is in Group 6A and has six valence electrons. It achieves octet by gaining two electrons to form S²- anion. Gaining three electrons to form S³¯does not make it octet, hence, S³¯ is not likely to form.
