Question

Write all four quantum number for 3f orbital

Answer 1

3f orbital don't exist......

Answer 2

The four quantum numbers are n(principal quantum number),l(azimuthal quantum number),ml(magnetic quantum number),ms(spin quantum number)

n designates the principal electron shell and it describes the most probable distance of electron from the nucleus. For 3f orbtal n=3

l determines the shape of the orbital and therefore angular disturbance. The  value of l can be 0 but not greater than n.(0 to(n-1)).For 3f orbital l=0,1,2

ml determines the number of orbital & the shape of the orbital & their orientation within a subshell. The value of ml is –l to+l. For 4f orbital ml=-2,-1,0,1,2

ms designates the direction of electron spin.

ms=+1/2,-1/2
