An electron is placed in a magnetic field b→ that is directed along a z axis. the energy difference between parallel and antiparallel alignments of the z component of the electron's spin magnetic moment with b→ is 5.00 × 10-25 j. what is the magnitude of b→?

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
