Atomic Structure and Electricity Check In

Front

What are the three smaller particles that make up atoms?

Back

Neutrons, electrons, and protons.

Front

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

Back

The ability for electrons to flow through the material.

Front

Describe the charges of electrons, protons, and neutrons.

Back

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

Front

What happens when a large number of free electrons gather at one end of a wire?

Back

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

Front

Why do birds only sit on one wire instead of having their feet on two different wires?

Back

When they are only on one wire, they are not making a closed circuit so they don't get electrocuted and cooked.

The basic unit of a chemical element, consisting of a nucleus surrounded by electrons.

Front

Back

Positive.

Front

What is the charge of a neutron?

Back

Neutral.

Front

What is the charge of an electron?

Back

Negative.

Front

What is an insulator?

Back

A material that does not allow electrons to flow freely, preventing the conduction of electricity.
