Which particles are negatively charged and zoom around an atom?

• neutrons
• electrons
• protons
• electric charge

Which particles are electrically neutral?

• protons
• electrons

What can cause static discharge (when you build up with friction-moving feet on carpet)?

• water molecules
• gravity
• the buildup of electrons
• protons

How can an atom have an overall negative charge?

• none

Which is an EFFECT of static electricity?

• neutral charge

• a girl shocks her brother
• you open an electric circuit

Why would socks become charged in the dryer?

• they became positive
• because they are insulators
• because they are conductors
• because they became charged in the dryer

What does a conductor do?

• allow electrons to travel easily
• prevents electrons from traveling through
• open an electric circuit
• stop electricity
