TYPES OF CHARGING PROCESS

REPORTED BY: LUCKY PRINCESS DELA CRUZ 7-NEWTON

LET’S DEFINE TERMS 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

INTRODUCTION

WHAT IS A POSITIVELY CHARGE?

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.

WHAT IS A NEGATIVELY CHARGE?

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.

HOW AN OBJECT BECOME A POSITIVELY CHARGE?

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.

HOW AN OBJECT BECOME A NEGATIVELY CHARGE?

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

CHARGING PROCESS

CHARGING BY FRICTION

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

CHARGING BY DIRECT CONTACT

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.

CHARGING BY CONDUCTION 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

CHARGING BY INDUCTION For this type of electric charge to occur, there doesn‛t actually have

to be anycontact 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.
