Rank the Material

Tests are performed with objects made of Materials A, B, C, and D. The table shows the results. Use these results to create a triboelectric series for A, B, C, and D.

A Triboelectric Series shows various materials ordered by their relative affinity (or love) for electrons. Materials located higher on the chart have a stronger affinity for electrons.

Triboelectric Series

Tap to select or deselect answer.

The chart at the right is a Triboelectric Series. It ranks materials according to their relative affinity (or love) for electrons. Materials located higher on the chart have a stronger affinity for electrons.
