Explain why one allotrope can conduct electricity?
One allotrope can conduct electricity if its structure allows for the movement of charged particles, such as electrons or ions. For example, in the case of graphene, its hexagonal lattice structure allows for the easy movement of electrons, enabling it to conduct electricity effectively.
Explain why you would not feel a shock if you touched the wooden part of a door?
Wood is an insulator, meaning it does not conduct electricity well. Since electricity needs a conductor to flow through, touching the wooden part of a door would not result in an electric shock.
What was Galvanis theory to explain his first investigation?
Galvani's theory to explain his first investigation was that animal electricity was responsible for the contraction of muscles, rather than an external source of electricity. He believed that the electricity originated within the muscle tissue itself, leading to the concept of "animal electricity."
What are the key principles and characteristics of the Bardeen model for semiconductors?
The key principles and characteristics of the Bardeen model for semiconductors include the concept of energy bands, electron-hole pairs, and the behavior of charge carriers in a semiconductor material. The model helps explain how semiconductors conduct electricity and how they can be used in electronic devices.
What Explain why conductors and insulator produce?
Conductors conduct electricity because they have free electrons that can move easily, allowing electric current to flow through them. Insulators, on the other hand, do not have free electrons and prevent electric current from passing through them. This difference in electron mobility determines whether a material acts as a conductor or an insulator.
Explain the effect of type of bonding on properties of materials?
The type of bonding in a material influences its properties. Materials with ionic bonds tend to have high melting and boiling points, are brittle, and conduct electricity when dissolved in water. Covalent bonded materials have lower melting and boiling points, can be flexible, and tend to be poor conductors of electricity. Metallic bonded materials have high thermal and electrical conductivity, malleability, and ductility.
Explain why one allotrope can conduct electricity?
One allotrope can conduct electricity if its structure allows for the movement of charged particles, such as electrons or ions. For example, in the case of graphene, its hexagonal lattice structure allows for the easy movement of electrons, enabling it to conduct electricity effectively.
Explain how Metallic bonds allow electricity to flow?
Metallic bonds are able to conduct electricity only when they are dissolved in a liquid substance or when in molten, this is because these conditions cause the metallic bond to break down and allow the electrons used in the bond to be delocalised and disposited around the molten or liquid. This sea of free electrons is then able to pass through a current and conduct electricity.
Explain why graphite conduct electricity but silicon carbide does not?
Because graphite has one free electron that is not involved in bonding. The one delocalized electron can be used to conduct electricity. However silicon carbide is tetrahedrally bonded to 4 carbon atoms. There is not free electrons in the arrangement. With no delocalized electron, silicon carbide is unable to conduct electricity.
How does metallic bonding explain the result at point c?
Metallic bonding involves the delocalization of electrons among metal atoms, creating a "sea of electrons" that allows for good electrical and thermal conductivity. At point C, the result can be explained by the strong forces of attraction between the delocalized electrons and metal cations, leading to the high melting point or other properties associated with metallic bonding.
Why the diode called polarity switch explain?
A diode will only conduct electricity if the polarity of the current is in the correct direction, because diodes can only conduct in one direction.
Solid CaCl2 does not conduct electricity explain why it is considered to be an electrolyte.?
Solid CaCl2 does not conduct electricity because the ions are in a fixed position and cannot move to carry an electric charge. However, it is considered an electrolyte because when dissolved in water, it dissociates into Ca2+ and Cl- ions, which are able to conduct electricity.
Explain why a substance needs to be either in a solution or molten for electrolysis to work?
Because electrolysis needs a liquid to conduct the electricity.
Will the solution of potassium chloride and water conduct electricity or not explain?
Yes, a solution of potassium chloride and water will conduct electricity. When potassium chloride (an electrolyte) dissolves in water, it dissociates into potassium ions and chloride ions which can carry electric current.
What do metallic bonds explain about the properties of gold?
Gold is a shiny, ductile material which is a good conductor of electricity and heat. All of these can be ascribed to its metallic bonds. What can't be explained so readily is its relative inertness and its color as metals are generally more reactive than gold and the majority are silvery white
Why understanding bonding is important for understanding molecules?
Understanding bonding is important for understanding molecules because it helps explain how atoms are held together to form different types of structures. The type of bonding (ionic, covalent, or metallic) influences a molecule's properties such as shape, polarity, and reactivity. Knowing the bonding within a molecule can also provide insight into its physical and chemical behavior.
Explain why do copper and iron conduct electricity?
Copper and iron conduct electricity due to the presence of free electrons in their atomic structure. These free electrons can move freely within the material, allowing for the flow of electric current. This property makes copper and iron good conductors of electricity.
