Document Summary
Sections 21. 1, 21. 2, 21. 3: 1 electric charge. The interaction between electric charges that are at rest (or nearly so) Two rods of like charge will repel each other, two rods of opposite charge will be attracted to each other. Electric charge and the structure of matter. The proton and neutron are combinations of other entities called quarks. Any numbers of subatomic particles carrying a fractional electric charge, building blocks of hadrons. Protons and neutrons make up the positively charged nucleus surrounded by the negatively charged electrons. The atom is held together by the attraction between the opposing charges the proton and neutrons are held together stable by the strong nuclear force. The positive charge of the proton has exactly the same magnitude as the negatively charged electron. The atom is of neutral charge when there are the same amount of protons and electrons. The most common way, an atom is charge is the addition or removal of electrons.
