1. The problem statement, all variables and given/known data Give a possible set of values of the four quantum numbers for all the electrons in boron atom and a nitrogen atom if each is in the ground state. I know the principles behind this. It comes from Zumdahl's Chemistry textbook (ninth edition, p. 345, number 95). The solutions manual however lists 5 examples for boron and 7 for nitrogen. However, doesn't this question ask for only ONE possible set of values? Shouldn't writing n=0 l=0 ml=0 ms=+1/2 for both boron and nitrogen enough to get the answer right? I'm a second language speaker! Why do they say "all the electrons"? What are they asking for?
