Orbital associated with the principle quantum number of n= 3 is 9 electrons show how ?
The principle quantum number (n) represents the energy level of an orbital. For n = 3, there are 3 sublevels: 3s, 3p, and 3d.
Each sublevel can hold a certain number of electrons:
- 3s sublevel can hold a maximum of 2 electrons
- 3p sublevel can hold a maximum of 6 electrons
- 3d sublevel can hold a maximum of 10 electrons
Adding up the maximum number of electrons that can be accommodated in each sublevel for n = 3:
2 (3s) + 6 (3p) + 10 (3d) = 18
Therefore, for n = 3, there can be a maximum of 18 electrons in total.
