Electrons, protons, and neutrons are the main subatomic particles that make up atoms. Electrons have a negative charge and orbit the nucleus, while protons have a positive charge in the nucleus. Neutrons have no charge. Atoms consist of a nucleus surrounded by electrons. When an object gains or loses electrons through friction or contact with another object, it becomes positively or negatively charged respectively, as gaining or losing electrons leaves the object with an excess or deficit of protons. Charging by contact occurs when a charged object transfers charge to a neutral object they touch.

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.
 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

4. 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.

5. 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.

6.  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.

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

9.  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

10.  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.

11.  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

12.  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.
