LaoPolythene has a higher affinity for gaining electrons than copper. When polythene is rubbed, electrons are transferred from one material to the other, leaving polythene with a net negative charge. Copper, on the other hand, has a lower affinity for gaining electrons, so it is more difficult to charge by rubbing.

What makes copper so conductive?
Copper is conductive due to its atomic structure, which allows for easy movement of electrons. Its outer electron shell is loosely bound, making it easy for electrons to move freely within the structure. This leads to high electrical conductivity in copper.
Why is copper easy to heat?
Copper has high thermal conductivity, which means it can quickly absorb and transfer heat energy. This makes it easy to heat up and manipulate for various applications such as heating coils and cooking pots. Additionally, copper has a low specific heat capacity, meaning it requires less energy to raise its temperature compared to other materials.
Advantages of polythene?
ADVANTAGES1. Polythene film is one of the most lightweight and durable packaging mediums available.2. Plastic packaging makes an important contribution to reducing food spoilage rates.3. Polythene ducting is compatible with most fans, heaters, air conditioners, air handling units, etc4. Polythene Bags use less energy and resources to create than glass or paper.5. Clear polythene allows recipients to view the contents (such as a magazine cover) prompting them to open immediately if the item is of interest or expectedDISADVANTAGES1. Polythene is not biodegradable, and if dumped in the soil causes harm to the plant life, as the toxic substances of polythene get blocked among the soil particles.2. Polythene threatens the life in the water bodies. The chemicals in polythene affects the survival of flora and fauna of the aquatic and marine Eco-systems.3. Polythene is also likely to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed.4. Polythene is harmful for animals if swallowed. It solidifies inside the abdominal cavity which ultimately becomes lethal to the animal.5. In most households poly bags are used to preserve food items. It has been found out, the colourful poly bags contains lead and cadmium which are toxic and cause adverse effects to human health.6. If polythene is burnt in open air Hydrogen cyanide which is carcinogenic (cancer causing) is released.7.Hydrogen cyanide causes environmental pollution and health hazards
Does copper offer an easy path for electrons to flow?
Yes, copper is a good conductor of electricity because its outer electron is loosely held and can move easily between atoms. This allows for easy flow of electrons through a copper wire, making it an ideal material for electrical wiring.
A reddish lustrous ductile malleable metal element?
The description provided matches the properties of copper. Copper is a reddish metal with a lustrous appearance. It is ductile and malleable, making it easy to shape into various forms and commonly used in electrical wiring and plumbing.
