Question

l values of subshells d, s, f, p are respectively

• A. 1, 2, 0, 3
• B. 3, 2, 1, 0
• C. 0, 1, 2, 3
• D. 2, 0, 3, 1

Answer 1

The Correct Option is D

To determine the correct l values for the subshells, it is essential to understand the concept of azimuthal quantum numbers. The azimuthal quantum number, denoted as l, determines the shape of the electron's orbital and corresponds to the different subshells in an atom. The l values are defined as follows:

• s-subshell: l=0
• p-subshell: l=1
• d-subshell: l=2
• f-subshell: l=3

By matching each subshell with its corresponding l value, we have the order:

• d: 2
• s: 0
• f: 3
• p: 1

Given the options, the sequence 2, 0, 3, 1 matches the l values of the subshells d, s, f, and p, respectively. 
Thus, the correct answer is: 2, 0, 3, 1

Answer 2

Explanation: 

The azimuthal quantum number (l) represents the shape of the orbital and is assigned as follows:

• s-subshell → l = 0
• p-subshell → l = 1
• d-subshell → l = 2
• f-subshell → l = 3

So the values of l for subshells d, s, f, p respectively are: 2, 0, 3, 1.

Correct Answer: 2, 0, 3, 1
