Why do some materials gain electrons while others lose electrons when rubbed together?

Electrons move much easier, having much less mass. Also, in all elements except hydrogen (more precisely, the isotope hydrogen-1), it takes a huge amount of energy to separate individual protons from the nucleus.

∙ 14y agoWhen one material is rubbed against another,frictional energy is generated.This energy when received or absorbed by electron helps electron in overcoming the forces of attraction that bounds it to nucleus.This energy is enough to break the force of attraction as mentioned now and transfer it to some where else, but not sufficient to reach the protons in nucleus at center and help them in overcoming their forces of attraction in nucleus.This is because protons are held together in nucleus with great amount of nuclear forces between them which cannot be easily overcomed or breaked.So, only electrons are found jumping from one to another material when they are rubbed against each other.

∙ 12y agobecause they have different changed electrons already so some material could be already positively charged and if you rub it with another material that is neutral it becomes positively charged too.

Can electrons move from one object to another when rubbed together?
The transfer of electrons from one object to another by direct contact is charging by conduction. The transfer of electrons form one uncharged object to another by rubbing the objects together is charging by friction.
When acetate is rubbed against your hair which loses and which gains electrons?
Acetate loses electrons, and the hair gains electrons. So acetate is negatively charged, meaning that the hair is positively charged.
What charge does a acetate rod acquire when rubbed with a duster?
The acetate rod loses electrons and becomes positively charged.
Is dust from two rocks rubbed together still a rock?
yes
An inflated rubber balloon is rubbed with a wool cloth until an excess of a billion electrons is on the balloon. what is the magnitude of the charge on the balloons?
1.602x10(-10)
How do materials become charged when rubbed together?
By electrons
What kind of materials can become electrically charge when they are rubbed together?
Insulators
What kind of materials become electrically charged when they are rubbed together?
Insulators
Which of these move from one object to another when two objects are rubbed together?
ELECTRONS
When two nonconducting materials such as hard rubber and fur are rubbed together what kind of electricity is generated?
Static
What happens when two different materials rubbed together?
You will create friction (a force pushing them both back) and heat.
What kind of materials can be electrically charged when they are rubbed together?
damp clothing and balloons that's all I know for now!
When two materials are rubbed together there is often a build - up of what kind of energy?
Heat energy is formed due to Friction.
How electric charge produced by friction in bodies?
When two objects rubbed together become charged due to electrons being transferred from one object to another.charging by friction is when two different materials are rubbed together or come in contact
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
Can glass rod be rubbed with any other material?
anything can be rubbed its a matter of the transfer of electrons
