Final answer:
To predict the ion formed by each element, we need additional information related to the composition of the freezer or the chemical reactions involved.
Step-by-step explanation:
The given question is related to predicting the ion formed by each element based on the energy usage of a certain brand of freezer.
However, the provided information does not directly relate to ion formation or elements. The information is about the energy usage of the freezer and its cost. To predict the ion formed by each element, we need to know the chemical properties of the elements and their tendency to gain or lose electrons.
Therefore, to predict the ion formed by each element, we need additional information related to the composition of the freezer or the chemical reactions involved.
