Question

write down the four quantum number values of 4f electron

Answer 1

Explanation:

The 4f sublevel has the quantum numbers n = 4 and 1 = 3. When l = 3, ml can only be +3, +2, +1, 0,-1, -2, and -3. Thus there are seven orbitals for the 4f sublevel. Each orbital can have electrons with +1/2 and -1/2 for me.
