释义

Ionic compound

原声例句
Crash Course 综合篇

Water, as we've discussed here before, is pretty dang good at dissolving stuff, ionic compounds in particular.

正如我们之前在这里讨论的那样, 水非常擅长溶解物质, 尤其是离子化合物。

Crash Course 综合篇

Now, when we name ionic compounds, we just say the cation first, and the anion second.

现在,当我们命名离子化合物时, 我们只是先说阳离子, 然后再说阴离子。

化学 Crash Course

Liquids made up of polar molecules are really good at dissolving solids that are composed of polar or ionic compounds.

由极性分子组成的液体非常擅长溶解由极性或离子化合物组成的固体。

Crash Course 综合篇

So the rich silver veins in Montana formed when water stuffed with ionic compounds ran through cracks in paleozoic limestone.

因此,当充满离子化合物的水流过古生代石灰岩的裂缝时,就形成了蒙大拿州丰富的银矿脉。

SciShow 合集

But we do know that central to the existence of these RSLs are perchlorates -- corrosive, toxic ionic compounds that are, troublingly, abundant on Mars.

但我们确实知道,这些 RSL 存在的核心是高氯酸盐——腐蚀性、有毒的离子化合物,令人不安的是,它们在火星上大量存在。

Crash Course 综合篇

But some ionic compounds can overcome even the dissolving power of water and when they form through reactions in solution, they fall out as a solid precipitate.

但是一些离子化合物甚至可以克服水的溶解能力,当它们通过溶液中的反应形成时, 它们会以固体沉淀物的形式脱落。

Crash Course 综合篇

Where conditions were right, silver ions in the water reacted with ionic compounds, or salts, in the limestone to make insoluble silver compounds that fell out of solution.

在条件合适的情况下, 水中的银离子会与石灰石中的离子化合物或盐发生反应,生成不溶性的银化合物, 这些化合物会从溶液中析出。

化学 Crash Course

Ionic solids are basically the solid forms of things we think of as ionic compounds like sodium chloride - or table salt, calcium carbonate - which is chalk and limestone, and magnesium sulfate - otherwise known as Epsom salt.

离子固体基本上是我们认为是离子化合物的固体形式,如氯化钠 - 或食盐、碳酸钙 - 白垩和石灰石,以及硫酸镁 - 也称为泻盐。

中文百科

离子化合物

氯化钠,一种离子化合物
Cristales de cloruro de sodio.
X-ray spectrometer developed by Bragg
Halite, the mineral form of sodium chloride, forms when salty water evaporates leaving the ions behind.

离子化合物,是由阴离子(Anion,带负电)和阳离子(Cation,带正电)组成,以本质上是库仑力的离子键相结合的化合物。离子化合物通常熔点和沸点较高,熔融时或电离产生其组成离子的水溶液中时能导电。 大部分离子化合物在常温下是固体,但也有一些常温下存在于液态离子化合物,它们通常是一些含有复杂有机组份的盐。注意液态离子化合物和离子化合物溶液的区别,后者中含有一些不具电性的分子。

Ionic compound 离子化合物

The crystal structure of sodium chloride, NaCl, a typical ionic compound. The purple spheres represent sodium cations, Na+, and the green spheres represent chloride anions, Cl−.
X-ray spectrometer developed by Bragg
Halite, the mineral form of sodium chloride, forms when salty water evaporates leaving the ions behind.
A schematic electron shell diagram of sodium and fluorine atoms undergoing a redox reaction to form sodium fluoride. Sodium loses its outer electron to give it a stable electron configuration, and this electron enters the fluorine atom exothermically. The oppositely charged ions – typically a great many of them – are then attracted to each other to form a solid.

In chemistry, an ionic compound is a chemical compound comprising ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium (Na) and chloride (Cl) in sodium chloride, or polyatomic species such as the ammonium (NH+
4
) and carbonate (CO2−
3
) ions in ammonium carbonate. Individual ions within an ionic compound usually have multiple nearest neighbours, so are not considered to be part of molecules, but instead part of a continuous three-dimensional network, usually in a crystalline structure.
