2.  ELECTRONS
Electrons are the subatomic particles
that orbit the nucleus of an atom.
They are
generally negative in charge and are
much smaller than the nucleus of the
atom.
 PROTONS
A proton is one of the most important
types of subatomic particles. Protons
combine with electrons and usually
neutrons to make atoms.

3.  NEUTRONS
A neutron is a subatomic particle
contained in the atomic nucleus. It has no
net electric charge, unlike the proton's
positive electric charge. The number of
neutrons in an atomic nucleus determines
the isotope of that element.
 ATOMS
The atom is a basic unit of matter that
consists of a dense central nucleus
surrounded by a cloud of negatively charged
electrons. It is made up of electrons, protons
and neutrons

5. When a process of oxidation takes place the element
acquires a unit positive charge.The number of protons
are more than the number of electrons in an element
which gives the element its positive charge as the
protons have a positive charge.

6. A negative charge is an electrical property of a particle at
the subatomic scale. Physically, it maintains the inverse
reaction to positively charged particles, creating a
electromagnetic field that demonstrates a certain level of
force, keeping both particles in a united and reactive state.

7.  Objects become positively charged if they lose
electrons.
 Objects become positively charged by having
electrons removed from the atoms that make
up the structure of the object in question.
Neutral atoms from which an electron is
removed (or several) are called ions, or
positive ions. The more electrons that are
removed from those atoms, the more positive
the object becomes.

8. To become negatively charged, an
object must gain electrons from
another object

10.  When you rub one material to another, they are charged by
friction. Material losing electron is positively charged and
material gaining electron is negatively charged.Amount of
gained and lost electron is equal to each other. In other words, we
can say that charges of the system are conserved.When you rub
glass rod to a silk, glass lose electron and positively charged and
silk gain electron and negatively charged

11.  A single spark produce by a charge transferred by contact
can cause dangerous fires and explosions
 When charging by contact occurs, one object is already
electrically charged.The other object may or may not be
charged as well.The Important thing to remember is that
for charge by contact to occur, there has to be a difference
in amount of charge already on the two objects.

12.  Bring a neutral object in contact with a
previously charged object. Both objects will
end up with the same charge although it
will be smaller than the initial charge

13.  For this type of electric charge to occur, there doesn‛t actually have to be any
contact between either object
 Remember:ANY neutrally charged object that comes in contact with a charged
object will be attracted to that object.The same works for induction, except they
don‛t touch.
 Example:The dust particle If it comes by, but does not touch, a charged
particle, it will push the opposite charge towards the side nearest the charged
particle.This will mean that one side of the dust particle will be negatively
charged, while the other side will be positively charged.
