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.

It has to do with glasses ability to give electron and silks natural ability to take them in there should be a table floating around on the interwebs which explains it in much greater detail. showing which materials give electrons easier than others and vice versa
Hope this has helped
I believe that the experiment consists of a GLASS Rod being rubbed with Silk or Fur!
When rubbed with Silk, Electrons are transferred to the Silk from the Glass...this leaves the Glass with a Net Positive set of IONS and a PLUS Charge.
When rubbed with Fur, Electrons are transferred to the Glass from the Fur...this leaves the Glass with a Net Negative set of IONS and a Negative Charge.
The electrons in the glass rod transfer into the silk by conduction. Since the glass rod has lost electrons it has more protons than electrons therefore making the glass rod positive.
No glass becomes positively charged and silk becomes negatively charged as electrons migrate right from glass to silk
For example as glass rob is rubbed with silk then glass becomes positively charged and silk negatively charged. This is mainly because of the transfer of electrons right from glass to silk. But in case of ebonite rod rubbed with fur electrons get transferred from fur to ebonite. So ebonite becomes negatively charged and fur positive charged Now in case of an atom or molecule one or more electrons get removed and so that atom or molecules become a positive ion. Same way as electron gets attached with a neutral atom then it becomes negative ion.
electrons are transferred from glass to rubber
Both are examples of static electricity generation. The big difference is the way the electricity is generated.
Were composed of no charge particles .
electrons are stripped away from the atoms in the glass and transferred to the cloth. This leaves the glass with more positive than negative charge, so you get a net positive charge.

When glass rod is rubbed with silk cloth it becomes positively charged and the silk cloth becomes negatively charged. This is because the glass rod looses electrons to the silk cloth which makes it positive and the silk cloth becomes negative.
It depends on what the rod is made of. For example, if it's a glass rod the glass will lose electrons to the nylon and become positively charged, and the nylon will gain electrons and become negatively charged. If the rod is made of aluminum or steel, the rod will gain electrons from the nylon and become negatively charged, and the nylon will become positively charged.
Yes , if elctron goes from fur to rod, fur is positively charged
electrons are transferred from glass to rubber
the silk will rub of the electrons on the silk, leaving the glass positively charged
on rubbing glass with silk, the former one becomes positively charged whereas the other negatively charged.
both get charged but with charges of opposite nature

If you move the material near the negative acetate strip and they repel each other, the material negatively charged. If they move towards each other, it is positively charged. If you move the material near the positive rod and they attract, the material is negatively charged. If they repel, it is positively charged. This is because opposite charges attract and same charges repel.
