Electrical Charges

Charging by Friction

Atoms
Everything is made up of atoms. Atoms are everywhere because
they are basically building blocks of matter. Atoms consists of protons with a
positive properties, electrons with negative properties and also neutrons with
neutral properties. If the atom looses or gains electrons, it gains an electric
charge. Gaining electrons will cause the atom to gain a negative charge while
losing electrons will cause the atom to gain a positive charge. The question
is, how to charge an object? There are many different ways to charge objects and one is charging by friction
Charging Objects with friction
Atoms have different properties and one of those properties
is the atoms "appetite" for electrons. Such property is called
electron affinity. To charge objects, we can rub them and move electrons from
object to object. When there are two objects, one will tend to gain atoms if
its electron affinity is superior to the other object. When the electron
affinity is superior to the other object rubbed against, it will then pull
electrons out of the object as a result from rubbing. Usually the
electrical charges are measured by "units". For example, -9 units. Hope
you enjoy!!!
