Electric Cells (pages 437 – 444)
Read section 11.1 in the text and complete the handout about Cells and Batteries. Batteries are
another way we generate electricity – but on a smaller scale. Batteries change chemical energy
into electrical energy (or flowing electrons).
Electric Circuit:
Voltaic cell:
A voltaic cell consists of two _______________________________ in a conducting solution
called an _____________________________.


One electrode is positive and one is negative.
The ___________________________ are connected through connecting wires and the
_______________________ begin to flow from negative to positive terminals because
they are ________________________ by the negative electrode and are
_____________________to the positive electrode.

4. Part of a voltaic cell is shown in the diagram on page 445.
a) Describe the role of electrons in a voltaic cell.
b) Which electrode will lose mass as the cell operates? Explain your answer.
5. List 5 different types of batteries/cells we use and indicate which properties make these
cells appropriate for their purpose (See table 11.1 on page441)
6. Label the following diagram with the correct terms.
