What make diamonds hard?
Diamonds are hard because of their unique atomic structure, which consists of carbon atoms bonded in a strong, three-dimensional network. This network of bonds makes diamonds extremely resistant to scratching and breaking, giving them their renowned hardness.
How is the hardness of a diamond related to the way it was formed?
Diamonds are formed into crystals with a perfect octahedral crystal habit. Hardness is associated "...with the crystal growth form, which is single-stage..." "The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material." All quotes according to Wikipedia research.
Minerals of this family tend to form long needlelike crystals?
The mineral family that tends to form long needlelike crystals is the amphibole group. Examples of minerals in this group include hornblende and tremolite. These minerals are silicate minerals with a double chain structure, which contributes to their characteristic needlelike crystal habit.
Why is diamond harder than graphite?
Diamond is harder than graphite because of its molecular structure. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, creating a strong and rigid network. This structure allows diamond to form strong covalent bonds, making it extremely hard. In contrast, graphite has a layered structure where each carbon atom is bonded to three others in a hexagonal lattice, with weak van der Waals forces between the layers, leading to its softer nature.
Why did Albert Einstein smoke?
Albert Einstein smoked mostly out of habit and to relieve stress. He started smoking when he was young and struggled with the addiction throughout his life, despite being aware of the health risks.
What is the difference between HABIT and FORM of a mineral?
The crystal habit is the way a mineral grows when it is uninhibited (not interfered with with other minerals or limits on the growing space).
Is it possible for a mineral to have a prismatic habit without having a cleavage?
Yes, a mineral can have a prismatic habit without exhibiting cleavage. Prismatic habit refers to the crystal form of a mineral that resembles elongated, prism-like shapes. Cleavage, on the other hand, is the tendency of a mineral to break along specific planes of weakness in its structure. A mineral may grow in a prismatic shape while lacking defined cleavage planes, resulting in a more conchoidal or uneven fracture instead.
The properties of a mineral crystal are determined by the arrangement of its particles and the?
types of atoms present in its chemical structure. These properties include hardness, color, luster, cleavage, and crystal habit. The geometric arrangement of the particles within the crystal lattice also affects its physical and optical properties.
How many planes does calcite have?
Calcite commonly exhibits three notable cleavage planes, which are oriented at approximately 75-degree angles to one another. This characteristic cleavage is a key feature that helps in identifying calcite among other minerals. Additionally, calcite can exhibit a rhombohedral crystal habit due to the arrangement of its atoms. Overall, its cleavage and crystal structure contribute to its unique optical properties.
Is it possible for a mineral to have a prismatic habit with out having any cleavagewhy or why not?
Yes, a mineral can exhibit a prismatic habit without having any cleavage. Prismatic habit refers to the elongated, column-like shape of the mineral's crystals, which can occur regardless of the internal atomic structure. Cleavage, on the other hand, is the tendency of a mineral to break along specific planes of weakness in its crystal structure. Some minerals may develop a prismatic form due to their growth conditions while lacking cleavable planes, resulting in a fracture instead of cleavage.
What type of crystal habit does muscovite display?
Muscovite generally displays a micaceous crystal habit, of thin flexible sheets.
What is a crystals habit?
A tabular crystal habit refers to the appearance of a mineral crystal as a somewhat flat, tablet shaped form.
Identify the physical properties that can be used to recognize and distinguish between minerals.?
Minerals can be recognized and distinguished based on physical properties such as color, luster, hardness, cleavage or fracture, specific gravity, and crystal habit. These properties can help in identifying different minerals as they each have unique characteristics that can be used for classification.
The shape of a crystal is called their?
A habit.
What mineral property observer number and angle of crystal faces?
sorry i do not know
What are the different properties of minerals?
The properties you would use to help distinguish one mineral from another are: crystal form and habit, hardness (mohs scale), magnetism, cleavage, streak color, luster, sometimes taste or smell, color can be pretty unreliable.
How can minerals be identifyed?
There are many factors to consider when identifying minerals. However, one factor cannot be used solely to determine the type of mineral. Geologists check for color, streak, hardness, cleavage, specific gravity, and crystal form and mineral habit.
