Electrostatic charge

  1. Sep 12, 2015 #1
    Someone told me that dust can not be charged becuase it does not have chemical polarity.
    Is that right?
    Should materials have chemical polarity to be charged?

    Dust particles can be charged, and this is completely independent of their chemistry.
