AAMC 8 atomic spin

This is the passage that went on about xrays and MRI's and three B fields and all that.

The question was "which atom has zero net spin?"

"Protons and neutrons have spin just as electrons do."

Is this general knowledge? I had no idea we account for protons and neutrons when counting net spin of an atom! Or is it just specific for this passage.

this is NMR stuff, use test taking skills here, (which of these doesn't fit in)--which would be the answer with odd numbers in the answer.

i did...i got the answer right.

i'm trying to understand more comprehensively.
