A number of energy transformations occur when water that is stored behind a dam is changed into electrical energy.

For each step listed, identify the energy transformation

Lake water flows downward through tunnels

Flowing water turns turbines.

Turbines generate electricity

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below.
