Spin Quantum Number and Electron Pairing The spin quantum number, denoted as mₛ , describes the intrinsic angular momentum or spin of the electron itself. For chlorine, the electrons occupy shells where n can be 1, 2, or 3, corresponding to the K, L, and M electron shells respectively.
Chlorine Quantum Numbers and Periodic Trends Unveiled
The first two shells are completely filled with eight electrons, while the valence shell, where chemical reactions occur, contains seven electrons configured with n equal to 3. This value is restricted to either +½ (often called spin-up) or -½ (spin-down).
In chlorine, the seven valence electrons populate these orbitals, filling the 3p x and 3p y orbitals completely with two electrons each, and placing the final electron within the 3p z orbital. Magnetic Quantum Number and Orientation The magnetic quantum number, represented as mₗ , specifies the orientation of the orbital in physical space relative to an external magnetic field.
Chlorine Quantum Numbers Periodic Trends Explanation
Consequently, within the filled 3p orbitals of chlorine, the paired electrons exhibit opposite spins, while the unpaired electron in the 3p z orbital possesses a spin of either +½ or -½, making chlorine a radical species with a single unpaired electron. These correspond to the three distinct 3p orbitals, often labeled as 3p x , 3p y , and 3p z.
