Atoms are made from electrons and atomic nuclei. Since the nucleus accounts for more than 99.9% of the atom’s mass, we can focus on the nucleus, or on the protons and neutrons it is made of. Protons and neutrons are made from quarks (each particle contains three quarks) and gluons. ...

"Electricity" is made of electrons, not protons. Nope. Electrons are a kind of energy particle. Wrong. "Electricity" carries zero mass because electrons have little mass. No. Positive charge is really just a loss of electrons. Wrong.
Because X-rays are scattered by electrons while neutrons are scattered by nuclei, the two probes give complementary information, which, when combined with the pronounced isotopic contrast available between deuterons and protons, enables experiments to be devised that allow the three site-site radial...
