Quantum Numbers
The maximum number of electrons that can have n = 3 and l = 2 is:
Select the correct option:
Solution
10
- Identify the subshell: n=3,l=2 corresponds to the 3d subshell.
- Determine Number of Orbitals: The number of orbitals in a subshell is given by (2l+1).
- For l=2: 2(2)+1=5 orbitals.
- Determine Number of Electrons: According to Pauli's Exclusion Principle, each orbital can hold a maximum of 2 electrons.
- Total capacity =5 orbitals×2 electrons/orbital=10 electrons.
