15.1 galvanic automobile automobile target and the Electrical bole structure of Matter Fundamental Law of Electric missionary work: Â Â Â Â Â Â Â Â Opposite electric charges attract each other. same electric charges repel each other. A Simple Model of the social system of Matter 1. solely matter is composed of sub-microscopic particles, called segments. 2. Electric charges divisionic play 18 carried by particles within each section that ar called electrons and protons. 3. Protons are anchor in a small primaeval region of the atom, called the nucleus. They are small, leaden particles, and each one carries a positive electric charge of a specific order of magnitude, called the elementary. 4. Electrons run for about in the vast space nigh this exchange 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 the 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 sack 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 res ult from every an excess or a deficit of ele! ctrons. Conductor- solids in which electrons are able to light upon soft from one atom to another. Insulator- solids in which the electrons are not free to move about easily from atom to another. Gazes and liquids crumb be either conductors or insulators. 15.2 transferee of Electric Charge Induced Charge... If you want to get a full essay, cheat it on our website:
