Current Question (ID: 7550)

Question:

$\text{Assertion (A): In the third energy level, there is no f subshell.}$\n\n$\text{Reason (R): For n = 3, the possible values of l are 0, 1, 2 and for f subshell l = 3.}$

Options:

1. $\text{Both (A) and (R) are true and (R) is the correct explanation of (A).}$
2. $\text{Both (A) and (R) are true but (R) is not the correct explanation of (A).}$
3. $\text{(A) is true but (R) is false.}$
4. $\text{(A) is false but (R) is true.}$

Solution:

$\text{Hint: for a n value, the value of l is 0 to n-1}$\n\n$\text{Explanation:}$\n\n$\text{For n = 3, the value of l is 0 to (3-1 = 2). Hence the value of l is 0, 1, and 2. For f, l value is 3 and for the third energy level,}$\n\n$\text{there is no f subshell because the maximum value of l for the third energy level is 2.}$\n\n$\text{Hence, both Assertion & Reason are true and the reason is the correct explanation of the assertion.}$
