Suppose an orbital may accommodate three electrons, then estimate the number of elements in 
period
Text Solution
Verified by ExpertsThe correct answer is:
D
In second period, 
-subhell and 
-subshell are filled having total orbitals as 
orbital. So, 
electrons may be accomdated if each orbital is filled with 3 electrons. So, as the capacity of 12 electrons is there, there will be 12 different electronic configuration available and hence the number of elements in the period will be 12.
