Charges and How They Behave

The AtomAtom : the smallest unit of an element

•Made up of smaller subatomic particles: protons, neutrons, and electrons

Charges

• Positive charge – there are more protons than electrons• Negative Charge – there are more

electrons than protons• Neutral Charge – there are the same

number of electrons and protons

Opposites Attract!!

The Law of Electric Charge:• Opposite charges attract each other

• Like charges (the same) repel each other

Friction (caused by rubbing two objects together)

A: before rubbing a balloon on hair, both have a neutral charge or the same number of electrons and protons

B: when the balloon is rubbed on the hair, negative charges are transferred from the hair to the balloon. The hair now has more protons or positive charges and the balloon has more electrons or negative charges .

Conductors and Insulators

Conductor cue card

• A material in which electrical charges can move easily

• Examples: copper, iron, salt water, Earth

Insulator cue card

• A material in which electrical charges cannot move easily

• Examples: wood, paper, oil, plastic, pure water

Electrical cords of most appliances and electrical tools are made of a conductor that is covered by and insulator
