If an object has the same number of positive and negative charges, its electrical charge is...

• positive
• negative
• neutral or no charge
• opposite

Static electricity is 

• The balance of electrical charge on an object
• The imbalance of electrical charge on an object
• The discharge of electrical charge
• The build up of protons in the nucleus of an atom 

Materials that tightly hold on to their electrons are considered 

• Good conductors
• Good insulators
• Good anti-static agents
• Useful for storing charge

Which one of these objects is a good insulator

• Copper wire
• Glass
• Aluminum 
• Gold

Materials that easily lose or accept electrons are considered

• Good conductors

• Good insulators

• Good anti-static agents

• Good for storing charge

What is the major difference between static electricity and current electricity?

• Current electricity involves a continuous flow of neutrons; static electricity is a sudden transfer of protons
• Current electricity can be deadly; static electricity is almost always safe
• In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons
• Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons
