How many electrons in an atom have the following quantum numbers?n = 4...
Explanation:
Quantum numbers:
- The principal quantum number (n) determines the main energy level or shell of an electron.
- The spin quantum number (s) determines the spin of an electron, with values of +1/2 or -1/2.
Given quantum numbers:
- n = 4 (fourth energy level)
- s = -1/2 (spin of the electron)
Calculation:
- For a given energy level (n), the maximum number of electrons that can be accommodated is given by 2n^2.
- For n = 4, the maximum number of electrons = 2 * 4^2 = 32.
Answer:
- The number of electrons with the given quantum numbers (n = 4, s = -1/2) is 16.
- Therefore, option 'D' (16) is the correct answer.

How many electrons in an atom have the following quantum numbers?n = 4...
n = 4
l = 0, 1 , 2 , 3
ml = 0, (-1, 0, +1), (-2, -1, 0, +1, +2), (-3, -2, -1, 0, +1, +2, +3)
Total number of electrons with ms = - 1/2 will be 16.
