If an H atom with a 1s configuration is placed in a magnetic field, the electron spin degeneracy will be removed and the number of states with different energies will be A. One B. Two C. Three D. None of the above
Homework Answers
Answer is B : Two
The term degeneracy refers the set of state described by different quantum numbers but having the same energy. The orbital degeneracy of any hydrogen atom energy level depends on the principal quantum number n,

(a) If an atom with one unpaired electron spin is placed in a magnetic field B, then there are two energy levels, corresponding to the two values of the quantum number ms. Calculate the energy difference AU between the states. (b) If the atom is irradiated it will absorb energy if the frequency v=4. This is phenomenon is called electron spin resonance. Calculate the frequency if B, is 27. In what part of the electromagnetic spectrum is this frequency?

A Review Constants Periodic Table Learning Goal: To use electron configuration to explain magnetic behavior. Electron configuration The magnetic behavior of an atom or ion depends on its electron configuration. An important property that results from the electron configuration of an atom or an ion is behavior in the presence of an external magnetic field. Due to the random orientations of electron spins most materials have no permanent magnetic effect without an external magnetic field. Part A Select the correct...

No Brief illustration 90.3 Spin-orbit coupiny The unpaired electron in the ground state of an alkali metal atom has l=0, so j=1. Because the orbital angular momen- tum is zero in this state, the spin-orbit coupling energy is zero (as is confirmed by settingj=s and 1=0 in eqn 9C.4). When the electron is excited to an orbital with I=1, it has orbital angular...
