3rd shell i.e. m shell has three subshells s,p,d which further contains 1,3,5 orbitals respectively and each orbitals with 2 elctrons ,overall (2×1)+(2×3)+(2×5)=2+6+10=18 . Similarly 4th the n shell one more subshell-f is added which contains 7 orbitals containing 14 electrons +18 of s p d giving 32 electrons.
