some substances hold onto electrons tighter than other substances, so they get the extra electrons.

What is the charge obtained by a neutral object if you are charging by contact?
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.
Materials that are neither good conductors nor good insulators?
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.
Explain the difference between induced charge separation and charging by induction?
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.
Why does an electric discharge occur?
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
What negatively charged particles move easily through materials?
An insulator
What happens when charging by rubbing?
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.

In a permanent magnet the magnetism comes from?
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.

How does a material acquire a positive electrical charge?
By losing electrons.
When a sock sticks on to another sock it is because protons move from one sock to the other or is it electrons?
It is because of electrons
How do paired electrons affect the magnetic properties of a material?
Because of a property called spin, electrons act like tiny magnets. Most of the time paired electrons contain opposite spins, meaning the material has a weak magnetic field. The more paired electrons a material has, the weaker the magnetic field in the material. Unpaired electrons attract and repel other material. This determines which materials unpaired electrons match up with and attract to form a magnetic domain.
What materials allow electricity to flow freely?
Because of freely moving of electrons in the material

Why do materials carry current?
Materials carry current because of the way the electrons of the material behave. Current is proportional to the number of electrons. If the electrons are loosely bound on the material then they are available to carry current along the material. Copper is a common metal who's configuration means that the electrons are loosely bound and as such is very good at carrying current. If on the other hand the electrons are tightly packed into the atoms in the material then they aren't available to carry current. Materials such as glass and plastic are good examples.
What bomd is formed when atoms share electrons?
When they share electrons it is covalent because they are codependent on each other, and ionic bonding is when they give electrons to another or receive electrons from another. that's how i remember it. Hope that helps :) x
Why does a friction cause a charge to develop?
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.
What is a material in which electrons do not easily flow?
An insulator is a material through which electrons do not easily flow. Insulators have a very high resistance.AnswerInsulators behave in the way they do because they contain insufficient numbers of charge curriers to support conduction. It has nothing to do with electrons being 'unable to flow easily'!
