CHEM Unit 2 Lessons 5-7 Review

Front

What is the charge of an electron?

Back

1-

Front

According to Coulomb's law, the force between two charges is directly proportional to what?

Back

The product of the charges

Front

What happens when objects in contact produce static?

Back

Electrons are removed from one object.

Front

What happens to the force when like or unlike charges are moved farther apart?

Back

It decreases significantly.

Front

An atom loses an electron. What type of charge does it have now?

Back

Positive.

Front

What is Coulomb's law?

Back

Coulomb's law states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects.

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge, while insulators do not.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electric charge due to the loss or gain of one or more electrons.

Front

What is the principle of conservation of charge?

Back

The principle of conservation of charge states that the total electric charge in an isolated system remains constant.
