some substances hold onto electrons tighter than other substances, so they get the extra electrons.
I believe you mean charging by contact as in electrons hitting the atom- then I suppose it would be a negative charge, because an electron is negative and it would make the charge of the opposing atom negative.
a material is neither a good conductor nor a perfect insulator because the number of free electrons determine the conductivity of a material.when we charge the material by electrification the transfer of electrons from one body to another takes place.and the atom is ionized because in each atom electrons are attracted by other material and net charge on the body is positive.but this is not permanent nor temporary.as we know that earth is a charged body and charge on conductor can be discharge by earthing a conductor and it is no more conductor.similarly in insulators the aoms locally polarize by bringing close to any charged body and the charge on insulator is temporary because there is deficiency of electrons.if we continously charged the insulator material finally a stage is reached when it becomes conductor e.g when clouds are attracted they charged the air and air becomes conductor and lightening strikes,we also know that air is insulator but due to excess charging air becomes conductor.
In induced charge separation, the charge of both substances remain neutral. There is no actual transferring of charges. During charging by induction, there is a transfer of charges by grounding.
It is because there are a build up of electrons on a material. If it is static it can be plastic or paper etc . The electrons are surplus to atomic requirements of the material so a negative charge will build up. If the charge is big enough the electrons will try and find a positive source to neutralise the charge. The only thing stopping it from doing so is the insulating material such as air
An insulator
In charging by rubbing, electrons move from one material to another because of the difference in affinity for electrons between the two materials. When two materials are rubbed together, one material gains electrons (becomes negatively charged) while the other loses electrons (becomes positively charged), resulting in the transfer of electrons between the materials.
Static electricity is the result of creating a charge by rubbing two objects together. The positively charged objected with accepted electrons from the negatively charged item giving it an electric charge.

It is because of electrons
By losing electrons.
Gold is an excellent conductor of heat because its electrons are free to move easily and carry thermal energy throughout the material. When heat is applied to gold, these free electrons transfer the thermal energy from one part of the material to another quickly, resulting in efficient heat conduction.
Mainly from the electrons, rotating around the nucleus. If the material is magnetized, then it is because several atoms are aligned in the same direction.Mainly from the electrons, rotating around the nucleus.

Electrons have difficulty moving around an electric current in certain materials because of resistance. Resistance is caused by collisions with other atoms and impurities in the material that hinder the flow of electrons. This resistance generates heat energy and limits the ability of electrons to move freely through the material.
An insulator is a material that prevents electrons from flowing freely. This is because insulators have tightly bound electrons that do not move easily in response to an electric field. Examples of insulators include rubber, glass, and wood.
When an object such as a balloon is charged by friction, it is because electrons are rubbed off of one object onto another. The electrons only change their location, otherwise they remain the same.
In this reaction, FeCl2 is the oxidizing agent because it causes another species to be reduced (lose electrons), while SnCl2 is the reducing agent because it causes another species to be oxidized (gain electrons).
