D
Total number of elements in V period will be 27​

Answer 1

Answer:

Explanation:

After this hypothetical condition, every orbital can have 3 electron.

As in second orbit, 4 orbital are there so total no. of electron is 4×3=12.  

Second period would have 12 elements.

Third period would have 12 elements.

Periodic table would contain 18×3/2=27 groups.
