What is a positively charged object?

Back

A positively charged object is one that has more protons than electrons, resulting in a net positive charge.

Front

What happens to an object when it becomes charged?

What is an example of a conductor?

Back

Copper is an example of a conductor.

Front

What is the role of electrons in charging an object?

Back

Electrons are the subatomic particles that can be gained or lost to create a charge on an object.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charge to flow easily, while insulators do not.

Front

What is the charge of an electron?

Back

Negative.

Front

What is the charge of a proton?

Back

Positive.

Front

How can an object become negatively charged?

Back

An object becomes negatively charged when it gains extra electrons.
