Basically, electrons are in each object, whether solid, liquid or gas. Here are outlined the position of electrons in the composition of an object.

  • Object is something that can be touched or seen with the naked eye.
  • Molecular is the smallest of things can still be divided again and still contains the chemical elements of the object.
  • Atom derived from the word which means not atomos indivisible, the smallest part of an object that can not be divided again. But after he was found redioktivitet symptoms, assuming it can not be maintained.Atom consists of electrons and atomic nuclei.

Based on the nature of the electron, it is divided into 3 categories:
  1. Conductor: is it easy to conduct the electrical charge, for example iron and copper
  2. Insulators: an object that is difficult to conduct electrical charges, for example plastic and wood
  3. Semi-conductor: an object load electric conductivity is not as good but better conductor than an insulator, such as transistors and diodes
