Write the electron configuration for the first excited state for N2 -that is, the state with the highest-energy electron moved to the next available energy level.
(a) Is the nitrogen in its first excited state diamagnetic or paramagnetic?
(b) Is the N¬N bond strength in the first excited state stronger or weaker compared to that in the ground state? Explain.
consider a 1g sample of radioactive californium z98 and a245. the half life of this isotope is 45 min. on average how
