Question

How Many Different $\mathrm{f}$ Orbitals Are There?

Answer 1

The number of orbitals present in $\mathrm{f}$ shell:

1. The number of shell is determined by principle quantum number($\mathrm{n}$). the shells are $\mathrm{K},\mathrm{L},\mathrm{M},\mathrm{N}$ shells. It is represented by $\mathrm{n}=1,2,3$and so on.
2. The shape of the orbital is determined by azimuthal quantum number($\mathrm{l}$). $\mathrm{l}=0$ to $\mathrm{n}$. so $\mathrm{l}=3$ for $\mathrm{f}$ orbitals.
3. The number of subshell are determined by magnetic quantum number($\mathrm{m}$). $\mathrm{m}=-\mathrm{l}$ to $+\mathrm{l}$. If $\mathrm{l}=3$, the number of subshell are$-3,-2,-1,0,1,2,3.$

So, there are seven subshells in $\mathrm{f}$ orbitals.
