1. what characteristic makes a diode-array spectrophotometer suitable for measuring the spectrum of the output of a chromatrography column (continuous monitoring) and a dispersive spectrophotometer not suitable? what is the disadvantage of the photodiode array spectrophotometer?

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
