What are electrons?

• Negatively charged particles that are fundamental components of atoms.

• Positively charged particles found in the nucleus of an atom.

• Neutral particles that orbit the nucleus of an atom.

• Particles that have no charge and are not part of an atom.

What type of energy is associated with moving electrons?

• Kinetic electrical energy because the electrons are in motion.

• Potential electrical energy due to the position of electrons.

• Thermal energy generated by electron movement.

• Chemical energy stored in electron bonds.

What happens when a negatively charged object touches a neutral object?

• Electrons can transfer from the negatively charged object to the neutral object, giving it a negative charge.

• The neutral object becomes positively charged by losing protons.

• The negatively charged object loses its charge completely.

• Nothing happens; they remain unchanged.

What is a conductor?

• A material that allows electrons to flow easily, facilitating the flow of electricity.

• A substance that prevents the flow of electricity.

• A type of electrical device that stores energy.

• A material that only conducts heat but not electricity.

What is static electricity?

• Static electricity is the buildup of electric charge on the surface of objects.

• Static electricity is the flow of electric current through a conductor.

• Static electricity is the energy produced by moving electrons in a circuit.

• Static electricity is the discharge of electricity through the air.

What is the relationship between electric charge and attraction?

• Opposite charges attract each other, while like charges repel.

• Like charges attract each other, while opposite charges repel.

• All charges attract each other regardless of their type.

• Electric charge has no effect on attraction.

How can you create static electricity?

• By rubbing two different materials together, such as feet on a carpet.

• By using a battery to generate a charge.

• By placing objects in a microwave.

• By heating metals until they glow.

What is the charge of a metal doorknob if it attracts negatively charged electrons?

• Negative electrical charge

• Neutral electrical charge

• Positive electrical charge

• Variable electrical charge

What is the role of electrons in electricity?

• The movement of electrons creates electric current, which powers devices.

• Electrons are responsible for the color of light emitted by devices.

• Electrons are used to store energy in batteries.

• Electrons have no significant role in electricity.
