Penny Battery Flashcard

Front

What is an ion?

Back

An ion is an element that has an unequal number of protons and electrons.

Front

What does the electrolyte produce in a battery?

Back

The electrolyte is responsible for producing hydrogen gas.

Front

What are the three essential components of a battery?

Back

A battery must have 2 electrodes and 1 electrolyte.

Front

Why can't protons move through a wire?

Back

Protons cannot move through the wire because they are too large.

Front

Where do electrons move when the penny battery is fully connected?

Back

Electrons will move to the copper wire.

Front

What is the role of electrodes in a battery?

Back

Electrodes are the conductors through which electric current enters or leaves the battery.

Front

What is the function of an electrolyte in a battery?

Back

The electrolyte facilitates the movement of ions, allowing the battery to generate electricity.

Front

What is the difference between an anode and a cathode?

Back

An anode is the electrode where oxidation occurs, while a cathode is where reduction takes place.

Front

What is oxidation in the context of a battery?

Back

Oxidation is the process where an atom or ion loses electrons.

Front

What is reduction in the context of a battery?

Back

Reduction is the process where an atom or ion gains electrons.
