What charge does a proton have?

• negative (-)
• positive (+)
• neutral or no charge (0)

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

• positive
• negative
• neutral or no charge
• opposite

What charge does an electron have?

• negative (-)
• positive (+)
• neutral or no charge (0)

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

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

Charge separation in clouds is one way

• that freezing rain occurs
• that lightning occurs
• that low pressure system occurs
• that a tornado occurs
