What else can I help you with?
Does pencil lead conduct electricity?
Pencil lead (aka graphite) DOES conduct electricity. It does this thanks to electron delocalization within the carbon layers. Since the valence electrons are free to move, they are able to conduct electricity.
Why does water conduct electricity while air does not?
Water contains ions and free electrons that can move and carry electric current, while air is composed mostly of molecules that do not contain free charges. This allows water to conduct electricity, while air does not conduct electricity well due to its lack of free charges.
Will a copper coin conduct electricity?
Each copper atom has lost one electron and become a positive ion. ... The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity. Therefore, copper is an outstanding material to use for conducting electricity! Hope it helped :)
Does Acid solutions conduct electricity?
Yes, acid solutions can conduct electricity because they contain ions that are free to move and carry electric charge. The concentration of ions in the solution determines its ability to conduct electricity.
How do you tell if something is non metal?
If an object does not conduct electricity, is not shiny, and is not malleable or ductile, it is likely a non-metal. Non-metals are generally poor conductors of heat and electricity, dull in appearance, and brittle. Additionally, non-metals tend to gain electrons when they form compounds.

Why is a metal found on the left side of the periodic table likely to conduct electricity?
Metals lose electrons to form cations. These ions help in conducting electricity.
Why does water conduct electricity while air does not?
Water contains ions and free electrons that can move and carry electric current, while air is composed mostly of molecules that do not contain free charges. This allows water to conduct electricity, while air does not conduct electricity well due to its lack of free charges.
How does soda conduct electricity?
Because it is a liquid , consisting free moving electrons

Yes, acid solutions can conduct electricity because they contain ions that are free to move and carry electric charge. The concentration of ions in the solution determines its ability to conduct electricity.
What makes an apple conduct electricity?
An apple can conduct electricity due to the presence of water and electrolytes inside it, which can help facilitate the flow of electrical current. The ions present in the juice of the apple also contribute to its ability to conduct electricity.
What is a better conductor for plastic newspaper or cotton balls?
Cotton balls are a better conductor of electricity compared to plastic newspaper because cotton is a natural fiber that contains moisture and minerals, which can help facilitate the flow of electrons. Plastic newspaper, on the other hand, is an insulator and does not conduct electricity well.
How charcoal conduct electricity?
Charcoal is an insulator. I had to use charcoal for a lab and see if it was a conductor or insulator, and we found out that it was an insulator since it can't help electrical/heat conductivity. -T :)

How do you make a project of sea of mobile electrons?
Creating a project centered on the concept of a "sea of mobile electrons" typically involves exploring conductivity and the behavior of electrons in conductive materials. You can conduct experiments with different metals and their ability to conduct electricity, or explore the principles of semiconductor physics. Additionally, incorporating visual aids like diagrams or simulations can help illustrate how electrons move through various materials. Engaging in hands-on activities, such as building simple circuits, can further enhance understanding of this fundamental concept in physics.
Is it true that ionic compounds cannot conduct electricity if they are dissolved in water?
Ionic compounds can conduct electricity when dissolved in water because the ions are free to move and carry the electric charge. The water molecules help to separate the ions from each other, allowing them to move and conduct electricity. This is why solutions of ionic compounds are known as electrolytes.
