What does it mean for an object to be charged?
When that happens,the atom is in a normal or neutral state. An entire atom becomes electrically charged when the number of electrons or protons stops being equal. The "extra" electron or proton isn't balanced by something inside the atom anymore and begins to be attracted to the protons or electrons in other atoms.
Positive and negative charges. Objects can be positively charged, negatively charged or neutral (no charge). A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged. Atoms or molecules that become charged are ions.
- Induction charging is a method used to charge an object without actually touching the object to any other charged object. An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process.
- In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object.
- The law of conservation of charge states that electric charge can neither be created nor destroyed. In a closed system, the amount of charge remains the same.
Methods. There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another.
- The first property is that same charges/objects repel and opposite charges/objects attract. This means that two positive charges or two negative charges will repel each other. A positive charge and a negative charge will attract each other. A neutral object will attract both a positive and a negative charge.
- Static electricity is a buildup of electric charges on objects. It occurs when electrons are transferred from one object to another. A sudden flow of electrons from one charged object to another is called static discharge.
- Electric charges are of two general types: positive and negative. Many fundamental, or subatomic, particles of matter have the property of electric charge. For example, electrons have negative charge and protons have positive charge, but neutrons have zero charge.
