Give the numbers for ml for a subshell of d orbitals Determi

Give the numbers for m_l for a subshell of d orbitals. Determine the energy change associated with the transition from n = 3 to n = 2 in the hydrogen atom. Additionally calculate wavelength and frequency of the electromagnetic radiation emitted during that transition. Place the following in order of increasing metallic character. C, Si, Ge, Sn, Pb

Solution

1. -2,-1,0,1,2.                                                                                           

2. The energy change is -3.03 × 10-19 J.                                                                    

3. C<Si<Ge<Sn<Pb.
