First, my thanks to the author for the considerable time spent in publishing All About Circuits. Second, in Volume I - DC, Basic Concepts of Electricity, the Static Electricity article tends to imply that all atoms contain electrons, protons, and neutrons, in particular one of the Review statements reads:
"All atoms contain particles called electrons, protons, and neutrons."
While all atoms have electrons and protons, not all have neutrons. For example, the most abundant atom, hydrogen, has one electron and one proton. Perhaps a better Review statement would be:
"While all atoms contain particles called electrons and protons, some atoms contain neutrons as well."
Of course, implementing this suggestion would mean altering the content of the article proper to briefly mention the same sentiment. That I leave that to the author and editors; much thought goes into revising text.
Thanks again for publishing All About Circuits.
