Question

Which of the following has pseudo-inert gas configuration in the (n-1) shell?

• A. Typical transition elements
• B. Zinc group elements
• C. Both of the above
• D. None of the above

Answer 1

Answer: (C)

Both of the above

pseudo-inert gas configuration means having 18 electron instead of 8 electrons in $(n-1)$ shell electronic configuration after gaining or loosing eletron.
And all d block elements including zinc group have this.
