Question

Explain the meaning of the symbol 4f^2.Write all the four quantum numbers for these electrons.

Answer 1

Answer:

Explanation:

we write 4f² , it means there are two electron present in 4f- orbital.

here 4 indicates principle quantum number , f indicates azimuthal quantum number . And 2 indicates number of electron present in 4f - orbital.

For 4f²

principle q.n , n = 4

azimuthal q.n, l = 3

Magnetic q.n, m = -3 , -2 , -1 , 0 , +1 , +2 , +3

spin quantum number , s = 1/2 or -1/2 .
