Does a glass rod rubbed with silk become negatively charged?

when a glass rod is rubbed with silk cloth, some of the electrons are removed from the atoms of the glass rod and deposited on the silk leaving negatively carged and glass positively charged Different materials have different electron affinities, meaning electrons will tend to gravitate towards certain materials over others. When silk is rubbed against a glass rod, the atoms of the rod and the atoms of the silk interact, and the silk atoms pull electrons from the rod's atoms. Thus, the silk winds up negatively charged and the rod becomes positively charged. Source: http://www.physicsclassroom.com/class/estatics/u8l2a.cfm
