A) First period
B) Second period
C) Fourth group
D) Ninth group
Correct Answer: B
Solution :
Each period consists of a series of elements whose atom have the same principal quantum no. \[(n)\] of the outer most shell i.e. In second period \[n=2\], this shell has four orbitals (one 2s and three \[2p\]) which can have eight electrons, hence second period contains 8 elements from atomic no. 3 to 10.
