Explain the meaning of the symbol 4f^(2). Write all the four quantum m

1.	Explain the meaning of the symbol 4f^(2). Write all the four quantum mumbers for these electrons.
Answer» Solution :`4f^(2)`: It means that the ELEMENT has 2 electrons in outermost 4f shell. QUANTUM number values are, n = principal quantum number = 4 l = AZIMUTHAL quantum number = 3 m = magnetic quantum number = `-3, -2` s = SPIN quantum number = ` +½, -½`
