Chapter 1 Physics of Electronics By Brent Mooney & Brian Wisneski

Chaper 1, the physics of Electronics: Chapter 1 introduces the reader to electronics.The introduction to electronics eduicates the reader of electrons, matter, elements, compounds, atoms, electrons, protons, neutrons, and nucleus.the electron is tiny particles that carry the energy to do work.Elements are the basic building materals that all matter is created from. Compounds are the composition of two or more elements. The atom is the most basic unit of all matter, and matter is anything which has weight and occupies space. The atom is made of Protons, Electrons, and Nuetrons. Atoms are the smallest particle into which a element can be divided. In the Nucleus of the atom are the protons and nuetrons and the electrons orbit around the nucleus.The nucleus is the center of the atom. A Bohr Model is used to show a physical drawling of an atom that has the same number of electrons, protons, and nuetrons as the element when it is not been ionized. Ions are atoms that are no longer in their neutral state. This usually happens when an atom either gains or loses a electron. Positive ions have more protons then electrons so they lose and electron and negatively charged ions have more electrons then protons so they gain an electrton. Matter- anything that has weight and occupies space Element- basic building materials of all matter Compound- material that is composed of two or more elements Molecule- the smallest particle of matter that still retains its characteristics Atom- the smallest particle to which an element can be reduced to Proton- positive charged subatomic particle in an atom located in the nucleus Nuetrons- have no charge and are located in the nucleus of an atom Electron- negatively charged subatomic particle in an atom that is located outside of the nucleus Nucleus- the center of an atom Ion- atom that is no longer in neutral state Balanced State- number of electrons is equal to the number of protons in an atom Electrostatic Field- field said to be had by all charged particles that surronds it and cause protons and electrons to attract each other
