Wool vs Cotton - electronegativity?

  1. May 17, 2014 #1
    Hi, If you rub woll against cotton, the cotton get's negatively charged and the wool positively charged. IS this because the atoms of the cotton are more electronegative? Or is it because the electrons of the wool attoms are more loosely held?

    For both reasons; I think.
    Cotton is more electronegative (then wool) implies Cotton atoms' (outer shell) electrons are more tightly held than wool.
