Question

1. if a material has a high electron affinity, what will occur when it is charged via friction with something with a low electron affinity

the object with higher electron affinity will gain an electron and end up negatively charged, while the object with a lower electron affinity will not gain or loose anything and remain neutral.
the object with higher electron affinity will loose a proton and end up negatively charged, while the object with a lower electron affinity will gain an proton and end up positively charged
the object with lower electron affinity will gain an electron and end up negatively charged, while the object with a higher electron affinity will loose an electron and end up positively charged.
the object with higher electron affinity will gain an electron and end up negatively charged, while the object with a lower electron affinity will loose an electron and end up positively charged.

Explanation:

Electron affinity refers to a material's tendency to attract and gain electrons. When two materials are rubbed together, the one with higher electron affinity will take electrons from the one with lower electron affinity. Gaining electrons gives a material a negative charge, while losing electrons leaves a material with a positive charge. Proton transfer does not occur in this type of frictional charging.

Answer:

The object with higher electron affinity will gain an electron and end up negatively charged, while the object with a lower electron affinity will loose an electron and end up positively charged.
