Answer» 1. c) Electric CURRENT2. b) ampere3. The elementary charge, usually denoted by e or sometimes q e is the electric charge carried by a single PROTON or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e .4. 5. Coulomb6. 7. Electrons and protons8. The number of PROTONS, neutrons, and electrons in an atom can be DETERMINED from a set of simple RULES. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. (not sure) |
