Question

4. What sub shell are possible in any n= 3 energy level? How many orbitals possible in this level?​

Answer 1

n=3

L=0(s),1(p),2(d)

m=0(3s),-1(3px),0(3py),+1(3pz),-2(3dxy),-1 (3dxz) ,0 (3dyz) ,+1 (3d x^2 - y^2 ),+2(3d z^2)

s=+,- 1/2

so there are 3 sub shells in n=3 i.e s,p,d

and there are 9 orbitals in them ie in s =0 orbitals, p=3 orbitals ,d= 5 orbitals

I HOPE THIS WILL HELP YOU
