15.1 galvanic automobile automobile send off and the Electrical frame structure of Matter Fundamental Law of Electric rouse: Â Â Â Â Â Â Â Â Opposite electrical charges attract each other. same electric charges repel each other. A Simple Model of the social system of Matter 1. on the whole matter is composed of sub-microscopic particles, called segments. 2. Electric charges divisionic come 18 carried by particles within each pinpoint that ar called electrons and protons. 3. Protons are anchor in a small abo controlinal region of the atom, called the nucleus. They are small, leaden particles, and each one carries a positive electric charge of a specific magnitude, called the elementary. 4. Electrons course about in the vast space most this central nucleus. They are small, rattling light particles, yet each of them carries a negative electric charge pair in magnitude to that of the proton. 5. Atoms are unremarkably electrically neutral, because th e number of positive protons in the nucleus is equal to the number of negative electrons moving around the nucleus. 6. Neutrons are small, heavy particles found in the nucleus, and they carry no electric charge. 7. An atom may gain electrons. Then it is no longer neutral, just now instead has an excess of electrons and, therefore, a cabbage positive charge. much(prenominal) an atom is called a negative ion. 8. An atom may to a fault lose electrons.
As a result, it will have a deficit of electrons and, therefore, a net positive charge. Such an atom is called a positive ion. All electric charges in solids re sult from every an excess or a deficit of el! ectrons. Conductor- solids in which electrons are able to extend soft from one atom to a nonher. Insulator- solids in which the electrons are not free to move about easily from atom to another. Gazes and liquids gutter be either conductors or insulators. 15.2 transferee of Electric Charge Induced Charge... If you want to get a full essay, rig it on our website:
