  • We know that an atom consists of electron, protons, and neutrons.
  • Each electron has a negative charge and each proton has a positive charge.
  • a neutron carries no charge and is therefore neutral.
  • In an atom, the number of electrons is equal to the number of protons and the atom is electrically neutral.
  • electrons may be added to or taken away from an atom.
  • this disturbs the electrical balance of the atom.
  • If an atom loses an electron it is left with an overall positive charge, since it has a proton in excess of those needed to balance the effect of its electrons.
  • such a charged atom is called a positive ion.
  • If an electron is added to an atom, it attains a negative charge. Such a charged atom is called a negative ion. A body having a number of ionized atoms is said to be electrically charged.
  • The SI unit of charge is the coulomb [C]
  • the measure of charge moved by one ampère of current in one moment of time [A s].
  • The thinking behind this definition is best left to later sections in this book.
  • an uncommonly enormous unit for everyday applications.

Elementary Charge

  • 1.60 × 10−19 coulombs
  • the size of the charge on an electron or proton
  • A charge is quantized in products of the basic charge.

Conservation of Charge

  • The complete charge of a shut framework is steady.
  • The universe is a shut framework.
  • At the point when subatomic particles are made, they don’t include or subtract charge from the universe in general.
