An atom has no charge because

• It has more electrons than protons

• It has more protons than electrons

• it has the same number of protons and electrons so they cancel the charges out leaving the atom electrically neutral

There are 6250 million billion protons in 1C of electric charge and 6250 million billion electrons in -1C of electric charge

• True

• False

The _____ says that a charge can be transferred between objects but cannot be created or destroyed

• Electrical Field Theory

• Newton's Third Law of Motion

• Law of Conservation of Charge

• Law of Conservation of Energy

Match the following:

• Touch

• Surrounds every electric charge and exerts a force that causes other electric charges to be attracted or repelled

• Conductors

• Discovered that the force between electrical charges depends on the amount of charge and distance between charges

• Insulators

• Materials where electrons move easily

• Charles Coulombs

• Electric charges do not have to do this to exert a force on each other

• Electric Field

• Materials where electrons do not move easily because they are tightly held to the atom

Your skin is an _______ conductor of electrical charges.

• effective

  (good)

• ineffective

  (not good)

The best electrical conductors are ​ (a)  

• metals
• woods
• nonmetals

Insulators make electrons not move easily because they are being held tightly together. This is why there is ​ (a)   wrapped around electrical wires.

• plastic
• tape
• wire

Match the following:

• Static Discharges

• Thunderclouds are mighty static electricity

• Electrolyte

• When enough + and - charges build up the charge discharges between the cloud and ground causing a collision of the electrical charge with atoms and molecules. This emission of light is called

• generators

• Touching a metal door knob and lightning are both

• lightning

• A large neutral object that is conductor of electrical charge

• Earth

• Moist paste with chemicals
