Static Electricity

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

What is static electricity caused by?

• A balance of power
• A balance of positive and negative charges
• . An imbalance of positive and negative charges
• An imbalance of protons and neutrons

If a substance has an excess number of electrons on its surface, what type of charge does it have?

• A negative charge
• A positive charge
• A neutral charge
• A nuclear charge

Which of the following atoms is considered neutral?

• An atom with five protons, six neutrons, and five electrons
•  An atom with five protons, five neutrons, and six electrons
• An atom with six protons, five neutrons, and five electrons
• An atom with six protons, six neutrons, and five electrons

Which of these materials is an insulator?

• Aluminum Paper
• Wool Sweater
• Copper Wire
• Silver Coin

How are electrons different from protons and neutrons?

• Protons and neutrons are negatively charged; electrons are positively charged
• Protons and neutrons exist inside atomic nuclei; electrons orbit atomic nuclei
• Electrons exist inside atomic nuclei; protons and neutrons orbit atomic nuclei
• Protons and neutrons are positively charged; electrons have no charge

What role does adhesion play in static electricity?

• It causes atomic nuclei to become unstable
•  It makes sure that atoms stay neutrally charged
• It prevents certain materials from giving away electrons
•  It pulls electrons from one surface toward another

What can you infer about any object that gives you a static shock when you touch it?

• . It's a conductor
•  It's an insulator
• It's negatively charged
•  It's positively charged

What happens when you touch a metal doorknob after rubbing your shoes on the carpet?

•  The doorknob sends a burst of electric current into your body
•  Millions of electrons go from your finger into the doorknob
• The doorknob sends millions of electrons into your finger
• Your finger becomes negatively charged

Lightning is a form of static electricity. What can you infer about what happens when lightning strikes the ground?

• Protons and neutrons are transferred from the clouds to the ground
• The ground becomes negatively charged
• . Electrons are transferred from the clouds to the ground
• An electric current is established between the clouds and the ground
