Atomic Structure and Electricity Quiz

What are the three smaller particles that make up atoms?

• Neutrons, electrons, and protons.

• Nutrients, elements, and photos.

• Nature, Protein Powder, and Phantoms.

• Electrons, protons, and photons.

Describe the charges of electrons, protons, and neutrons.

• They all exist together when you turn them on.

• Electrons have a negative charge, protons have a positive charge, and neutrons are neutral.

• Electrons are neutral, protons have a positive charge, and neutrons have a negative charge.

• Electrons have a negative charge, protons are neutral, and neutrons have a positive charge.

Where are neutrons and protons located within an atom?

• In the electron cloud.

• In the outer shell.

• In the nucleus.

• In the valence shell.

What determines whether a material is classified as an insulator or a conductor?

• The number of protons in the material.

• The tightness with which a material holds onto its electrons.

• The number of neutrons in the material.

• The density of the material.

Explain how current electricity differs from static electricity.

• Current electricity involves the build-up of charge on an object at rest, while static electricity involves the flow of electrons through a conductor.

• Current electricity involves the flow of electrons through a conductor, while static electricity involves a build-up of charge on an object at rest.

• Current electricity involves the flow of protons through a conductor, while static electricity involves a build-up of charge on an object at rest.

• Current electricity involves the build-up of charge on an object at rest, while static electricity involves the flow of protons through a conductor.

What causes static electricity to occur?

• When an object loses electrons through friction.

• When an object accumulates extra electrons through friction.

• When an object gains protons through friction.

• When an object loses its direction and needs a map to help it.

Name two sources of electricity mentioned in the video that involve natural resources.

• Natural gas and coal.

• Nuclear power and wind.

• Water (hydro) and solar energy.

• All of the above.

What happens when a large number of free electrons accumulate at one end of a conductor?

• Electrons with the same charge attract each other, causing them to stay still.

• Electrons with the same charge repel each other, causing them to move and flow as an electric current.

• Electrons with the same charge attract each other, causing them to move and flow as an electric current.

• Electrons with the same charge party and dance with each other, causing them to stay still.

How is current electricity generated?

• By the build-up of charge on an object at rest.

• By the flow of protons through a conductor.

• By the flow of electrons through a conductor.

• By the accumulation of chocolate in a conductor.

What practical purpose does electricity serve, as mentioned in the video?

• Electricity powers our homes and is used as a primary energy source.

• Electricity powers our homes and is used as a secondary energy source converted from other forms of energy.

• Electricity powers our homes and is used as a renewable energy source.

• Electricity powers the world and all the creatures on it.
