Materials that hold electrons tightly typically have a high electrical resistivity, such as insulators like rubber, glass, or plastic. These materials do not conduct electricity easily because the electrons are strongly bound to the atoms and do not move freely.

How could you use a pith ball electroscope to learn which material holds onto its electrons more strongly?
You could use the pith ball electroscope to test different materials by charging it with the materials and observing the behavior of the pith ball. If the pith ball is deflected more when charged with a particular material, it indicates that the material holds onto its electrons more strongly.
What is an material that does not transfer charge easily?
An insulator is a material that does not transfer charge easily. Insulators have tightly bound electrons that do not move freely, which prevents the flow of electric current through the material. Examples of insulators include rubber, glass, and plastic.
Are there loosely bound electrons in insulators?
In insulators, electrons are tightly bound to their respective atoms, which restricts their movement and makes the material a poor conductor of electricity. This lack of freely moving electrons is why insulators are used to prevent the flow of electric current.
How do the valence electron of mercury make it bonding weaks?
Mercury has weak bonding tendencies due to its unique electron configuration, which includes a filled inner electron shell that shields the outermost electrons from effective interactions with other atoms. This makes it challenging for mercury to form strong bonds with other elements.
How do you account for fair and poor conductors of electricity?
Fair conductors of electricity have some electrons that can move freely, allowing for the flow of electricity. Poor conductors have fewer free electrons, hindering the flow of electricity. This difference is due to the material's atomic structure and its ability to facilitate the movement of charged particles.
What is a conductor and a insulater?
A conductor is any material in which electrons are free to flow, whereas an insulator is any material in which the electrons are tightly bound to the molecules with which they are associated.
How can friction be useful to us?
When two materials rub together, the loosely held electrons of one material move to the material with the more tightly held electrons.
Is a conductor a material that does not easily give up or take on electrons?
A conductor is a material that easily allows the flow of electrons, making it a good medium for conducting electricity. It does not hold onto electrons tightly, allowing them to move freely within the material, unlike insulators which resist the flow of electrons.
In a good insulator electrons are usually?
In a good insulator, electrons are tightly bound to their atoms and have limited freedom to move. Due to this strong binding, insulators do not conduct electricity well as the electrons cannot easily flow through the material.
What is a material through which electrons do not easily flow?
insulator
How friction can be used to transfer electrons?
Friction can transfer electrons by causing the rubbing of materials together, which results in the transfer of electrons from one material to another. This transfer occurs due to the buildup of electrostatic charges on the surface of the materials, leading to the movement of electrons from one material to the other.
A material that prevents electrons from flowing freely is called what?
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.
Which element holds its electrons most tightly?
Fluorine holds its electrons most tightly among the elements. This is because fluorine has the highest electronegativity value on the periodic table. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
Do some materials hold onto electrons more tightly than others when charging by rubbing to occur?
Yes, some materials hold onto electrons more tightly than others. This property is known as electron affinity, and materials with higher electron affinities tend to hold onto electrons more strongly when charged by rubbing. Materials like rubber or wool have higher electron affinities compared to materials like silk or glass.
You are given two objects made from different materials. How could you use a pith ball electroscope to learn which material holds on to its electrons more strongly?
You can charge each material by rubbing it with a cloth to transfer electrons. Then, bring each material close to the pith ball electroscope without touching it. The material that causes the pith ball to deflect more significantly is the one that holds on to its electrons more strongly.
What happens to the electrons in an insulator?
In an insulator, electrons are tightly bound to their atoms or molecules and are not free to move around. This makes insulators poor conductors of electricity because the electrons cannot flow easily through the material.
What force holds inner planets tightly to the sun?
Gravity :) (Gravity also holds the outer planets tightly to the Sun.)
