晶格和晶体之间的差异

晶格与晶体

晶格和水晶是两个单词。这两个词可以互换使用，但是两者之间的区别很小。

格子

晶格是一种数学现象。在化学中，我们可以看到不同类型的离子和共价晶格。它可以定义为固体，它具有基本单元的三维顺序排列。基本单元可以是原子，分子或离子。晶格是具有这些重复基本单元的晶体结构。当离子与离子键相连时，它们会形成离子晶体。例如，可以采取氯化钠。钠是1组金属，因此形成+1带电的阳离子。氯是非金属的，具有形成-1带电阴离子的能力。在晶格中，每个钠离子都被六个氯离子包围，每个氯离子被六个钠离子包围。 Due to all the attractions between ions, the lattice structure is more stable. The number of ions present in the lattice varies with the size of it. Lattice energy or enthalpy of lattice is the measure of the strength of the ionic bonds in the lattice. Normally lattice enthalpy is exothermic.

钻石和石英是三维共价晶格的两个例子。钻石仅由碳原子组成，每个碳原子都共价粘结到其他四个碳原子以形成晶格结构。因此，每个碳原子都有四面体排列。通过形成这样的结构，钻石获得了高稳定性。（已知钻石是最强的矿物质之一。）石英或二氧化硅也具有共价键，但它们在硅和氧原子（不同原子的晶格）之间。这两个共价晶格都有一个很高的熔点，并且无法传导电力。

水晶

水晶是固体,有序结构and symmetry. The atoms, molecules, or ions in crystals are arranged in a particular manner, thus have a long-range order. Crystals are naturally occurring on earth as large crystalline rocks, such as quartz, granite. Crystals are formed by living organisms too. For example, calcite is produced by mollusks. There are water-based crystals in the form of snow, ice or glaciers. Crystals can be categorized according to their physical and chemical properties. They are covalent crystals (e.g. diamond), metallic crystals (e.g. pyrite), ionic crystals (e.g. sodium chloride) and molecular crystals (e.g. sugar). Crystals can have different shapes and colors. Crystals have an aesthetic value, and it is believed to have healing properties; thus, people use them to make jewelry.

晶格和晶体有什么区别？ •晶格描述了晶体的结构。当一组分子倾向于在晶格点反复排列每个单元时，制成晶体。 •在晶体结构中，有一种布置原子或单元的模式。这些图案位于晶格的点上。这些晶格点以三维有序的方式排列。
