Question

(A) Magnetic quantum number can have the value 0....., (n - 1) .
(R) Magnetic quantum number specifies the number of orbitals.

• A. Both (R) and (A) are true and reason is the. correct explanation of assertion
• B. Both (R) and (A) are true but reason is not correct explanation of assertion
• C. Assertion (A) is true but reason (R) is false
• D. Assertion (A) and reason (R) both are false
• E. Assertion (A) is false but reason (R) is true

Answer 1

The correct option is A Both (R) and (A) are true and reason is the. correct explanation of assertion

Magnetic quantum number $l$ signifies number of orbitals
$l$ values are 0,1,2,3 which represents s,p,d,f respectively
For a given value of n,$l$ values are 0 to (n-1)

Both (R) and (A) are true and reason is the. correct explanation of assertion.

Hence option A is correct.
