Wh ich of the followin g is not per missible arrangement of electrons in an atom? [2009]
- a)n = 5, l = 3, m = 0, s = + 1/2
- b)n = 3, l = 2, m = – 3, s = – 1/2
- c)n = 3, l = 2, m = – 2, s = – 1/2
- d)n = 4, l = 0, m = 0, s = – 1/2
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Wh ich of the followin g is not per missible arrangement of electrons ...
m = 2 l +1, thus for l = 2, m = 5, hence values of m will be – 2, –1, 0, + 1, + 2.
Therefore for l = 2, m cannot have the value– 3.
Therefore for l = 2, m cannot have the value– 3.

Wh ich of the followin g is not per missible arrangement of electrons ...
Explanation:
Permissible arrangement of electrons in an atom:
- In an atom, the electrons are arranged in different energy levels represented by the principal quantum number (n).
- Each energy level can have sublevels represented by the azimuthal quantum number (l).
- The magnetic quantum number (m) specifies the orientation of the orbital in space.
- The spin quantum number (s) specifies the spin of the electron.
Analysis of the given options:
- Option a: n = 5, l = 3, m = 0, s = +1/2 - This is a permissible arrangement as it follows the rules of quantum numbers.
- Option b: n = 3, l = 2, m = -3, s = -1/2 - This arrangement is not permissible because the magnetic quantum number (m) cannot be greater than the azimuthal quantum number (l) in magnitude.
- Option c: n = 3, l = 2, m = -2, s = -1/2 - This is a permissible arrangement as it follows the rules of quantum numbers.
- Option d: n = 4, l = 0, m = 0, s = -1/2 - This is a permissible arrangement as it follows the rules of quantum numbers.
Therefore, the correct answer is option 'B' because the magnetic quantum number (m) is not valid for the given values of n and l.
