Question

electron affinity
triboelectric charging
during triboelectric charging, es are transferred from the material with the
least e affinity (making it +) to the material with the greatest e affinity (making
it -)
example: glass is rubbed with silk and the glass
becomes +. which material - glass or silk - has the
greatest affinity for es?
multiple - choice question
which object has the greater electron affinity?
silk
glass
rewatch

Explanation:

During triboelectric charging, electrons are transferred from the material with lower electron affinity (which becomes positively charged) to the material with higher electron affinity (which becomes negatively charged). In the example, glass becomes + (loses electrons), so silk (which gains electrons) must have a greater electron affinity.

Answer:

Silk
