Predict the multiplet you would expect for coupling to three equivalent spin-5/2 nuclei.

What is the degeneracy of the n = 6 shell of atomic hydrogen considering (n,l,me) and no magnetic field?

The magnetic dipole moment of a deuterium nucleus is about 0.0005 Bohr magneton. What does this imply about the pres- ence of an electron in the nucleus, as the proton-electron model requires?

Write down the ground state electronic structure for Rb by inserting the correct integer numbers in the boxes below. Leave a box empty, or insert a zero if you want to indicate no electrons occupy that specific orbital. You can look at the Periodic Table (Section 5.4 of Unit 21) to establish the number of electrons in Rb. 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d Select from the list below one element that you expect would have similar chemical properties to Rb. ○ Li Mg OCI B S As
