What property of diamonds makes them valuable for applications requiring tough materials?

Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 1
Diamonds are valued in applications requiring tough materials due to their exceptional hardness. This hardness allows diamonds to resist scratching and abrasion, making them ideal for uses such as cutting tools and abrasives. Despite their hardness, it is important to note that diamonds are also brittle, meaning they can shatter under force contrary to what many people might assume about their strength.

Why is it crucial to differentiate between hardness and strength in materials like diamonds?

Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 2
Distinguishing between hardness and strength is critical in understanding the properties of materials like diamonds. Hardness specifically refers to a material's resistance to scratching and abrasion, while strength indicates its ability to withstand external forces without breaking. This differentiation is essential because a material can be hard and still lack strength, as is the case with diamonds, which are hard but brittle.

What property of graphite allows it to conduct electricity?

Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 3
The property of graphite that enables it to conduct electricity is the presence of delocalized electrons. These free electrons can move freely throughout the structure of graphite, facilitating its ability to conduct electricity. This unique characteristic arises from the layered structure of graphite, where each carbon atom is connected to three others, forming hexagonal shapes.

In what applications is graphite commonly used?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 4
Graphite finds common usage as an industrial lubricant in various applications such as engines and locks. Additionally, it is utilized to create non-reactive electrodes for processes like electrolysis. These applications leverage graphite's properties such as its soft and slippery nature, as well as its ability to conduct electricity, making it a valuable material in diverse industrial processes.

What distinguishes the bonding structures of diamond and graphite, leading to their contrasting physical properties?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 5
The distinct physical properties of diamond and graphite stem from their bonding structures. In diamond, each carbon atom forms bonds with four other carbon atoms, resulting in a tetrahedral structure with uniform, strong covalent bonds. This arrangement leads to the absence of intermolecular forces in diamond, contributing to its hardness and high melting point. On the other hand, graphite's carbon atoms form bonds with three others, creating layers of hexagonal structures. While the covalent bonds within these layers are robust, the weak intermolecular forces between the layers allow them to slide over each other, giving graphite its lubricating properties and softness.

What characteristic is shared between Silicon(IV) oxide (SiO2) and diamond?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 6
Silicon(IV) oxide (SiO2) shares the characteristic of insolubility in water with diamond. This property is a result of the strong covalent bonds present in both substances, which prevent water molecules from effectively breaking down these structures to enable dissolution. Insolubility in water is a key feature of substances with strong covalent bonds like SiO2 and diamond.

What property of metals allows them to conduct electricity effectively?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 7
Metals conduct electricity due to the availability of free electrons that can move through the structure to carry charge. When electrons enter one end of the metal, a delocalized electron displaces itself from the other end, facilitating the flow of electrons and the conduction of electricity. This property is vital in various applications where electrical conductivity is required, such as in wiring and electronic components.

What characteristic of metallic bonds contributes to the strength and flexibility of metals?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 8
The maintenance of metallic bonds, where outer electrons are not associated with specific metal atoms but move freely as delocalized electrons, contributes significantly to the strength and flexibility of metals. This allows for the movement of positive ion layers relative to one another without breaking the overall integrity of the metallic structure. As a result, metals can maintain their strength while also being malleable and ductile, enabling processes like hammering, bending, and wire drawing without fracturing.

What property of metals allows them to endure processes like hammering and being drawn into wires without undergoing fracture?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 9
The malleability and ductility of metals are attributed to the positive ion layers' ability to shift relative to one another, allowing for different arrangements within the metal structure. This property enables metals to exhibit strength along with flexibility, making them capable of enduring processes like hammering, bending, and being drawn into wires without undergoing fracture. This unique characteristic is crucial in various industrial processes where metals need to be shaped and formed without breaking.

Why do metals possess high melting and boiling points?
Detailed Solution for Test: Graphite and Diamond & Silicon Oxide & Metallic Bonding - Question 10
Metals possess high melting and boiling points primarily due to the presence of strong metallic bonds within their structures. Significant heat energy is required to break these bonds, which contributes to the high melting and boiling points of metals. This strength in bonding allows metals to maintain their solid state at high temperatures.
