Properties of metals as high boiling point, high melting point, malleability, ductility, electrical conductivity, thermal conductivity, lustre are explained by the theory of metallic bonds.
The electron sea model explains why metals are malleable and good conductors of electricity. In this model, metal atoms donate their outer electrons to form a "sea" of delocalized electrons that are free to move throughout the structure, contributing to the metal's properties.
Water has a covalent bond because it is formed by the sharing of electrons between the oxygen and hydrogen atoms. The difference in electronegativity between oxygen and hydrogen allows for the electrons to be shared, creating a stable molecule.
Copper is a good conductor of electricity because it has a high electron mobility, meaning that its electrons can move easily through the material. Additionally, copper atoms have a single free electron in their outer shell, which allows them to carry electrical charge efficiently. Its crystalline structure also contributes to its conductivity by allowing electrons to flow with minimal resistance.
Yes, covalent bonding between oxygen and hydrogen atoms allows water to have unique properties such as high surface tension, high specific heat capacity, and the ability to form hydrogen bonds. These properties are essential for the biological functions and the overall existence of living organisms.
The property that explains the differences in ability of copper and rubber to transmit electricity is conductivity. Copper has high electrical conductivity due to its free-flowing electrons, allowing it to easily transmit electricity. Rubber, on the other hand, is an insulator and has low electrical conductivity, as its electrons are tightly bound and unable to move freely to conduct electricity.
The pool of shared electrons in metals explains their high electrical conductivity, as the delocalized electrons are free to move and carry electric charge throughout the material. It also explains their malleability and ductility, as the electron cloud allows atoms to slide over each other without breaking bonds easily.
high hardness
The conductivity of electrolytes in solution is due to the presence of charged ions that can move freely and carry an electric current. When dissolved in water, electrolytes dissociate into positive and negative ions, allowing them to conduct electricity. The higher the concentration of electrolytes in the solution, the higher the conductivity.
This depends on the nature of solvent and solute, concentration of solute, temperature, etc.
Thermal conductivity is the concept that explains why some objects heat up faster than others when exposed to the same heat source. Materials with higher thermal conductivity can conduct heat more efficiently, leading to quicker heating. Materials with low thermal conductivity may take longer to reach the same temperature.
Thermal conductivity is the term that explains why some materials heat up more quickly than others. Materials with high thermal conductivity allow heat to flow through them easily, resulting in quicker heating. Conversely, materials with low thermal conductivity take longer to heat up because they impede the flow of heat.
Electric conduction is due to coherent movement of electrons (electrical charges) trough the material. More free to move the electrons are, bigger is the conductivity. The "molecolar structure", or better the strenght of the nucleus-electrons bond determine the freedom of the electrons, and so the material's conductivity. In particular, in metals there are a lot of quasi-totally free electrons, that explains why metals are good conductors.

Another name for the molecular orbital theory of bonding in metals is the band theory. Band theory describes how atomic orbitals combine to form energy bands, which explains the electrical conductivity and other properties of metals. It highlights the overlap of atomic orbitals in a solid, leading to the formation of conduction and valence bands.
The band theory better explains the electrical conductivity of materials, particularly in semiconductors and insulators. Unlike the sea of electrons model, which treats electrons as delocalized particles in a fixed lattice, band theory accounts for the formation of energy bands and band gaps that dictate how electrons move through a material. This distinction allows for a more accurate understanding of how impurities and temperature variations can affect conductivity, making it essential for explaining the behavior of semiconductors in electronics.
