Question

Find all four quantum numbers of last electron of nickel

Answer 1

Answer:

Explanation:

atomic number(Z) of nickel = 28

so number of electrons = 28

electronic configurations of nickel :

1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8

four Quantum numbers for differentiating electron or last electron of nickel:

1. principle Quantum number : 3
2. angular momentum Quantum number : 2
3. magnetic momentum Quantum number : 0
4. spin Quantum number: -1/2
