Statement-1 : The `5^(th)` period of periodic table contains 18 elements not 32.
Statement-2 : n=5,l=0,1,2,3. The order in which the energy of available orbitals 4d, 5s, 5p increases is `5slt4dlt5p` and the total number of orbitals available are 9 and thus 18 electrons can be accomodated.
A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.
