CH104: Chemistry and the Environment

In chemistry , an ionic compound is a chemical compound composed of 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. 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. Ionic compounds usually form crystalline structures when solid. Ionic compounds without these ions are also known as salts and can be formed by acid—base reactions. Ionic compounds can also be produced from their constituent ions by evaporation of their solvent , precipitation , freezing , a solid-state reaction , or the electron transfer reaction of reactive metals with reactive non-metals, such as halogen gases. Ionic compounds typically have high melting and boiling points , and are hard and brittle.

BIG Idea Atoms in ionic compounds are held together by chemical bonds formed by the attraction of oppositely charged ions. Most recreational scuba divers limit their dives to 40 m or less. The deepest scuba dive was to a depth of more than m. Divers carry the air that they breathe in a tank, and must follow special procedures to avoid oxygen toxicity, nitrogen narcosis, and the bends. For a material to conduct an electric current, it must contain charged particles that can move throughout the substance.

Identify the compound whose solubility you want to check. It can be helpful to write out the empirical formula so you can identify the ions that make up the compound. Look up each ion in the solubility rules. Check the left-hand column for the general rule, and look in the right-hand column to make sure you noted any exceptions. Therefore, it will not be wrong to say that ions form ionic compounds.

Этот враждебный мир заполняли рабочие мостки, фреоновые трубки и пропасть глубиной 136 футов, на дне которой располагались генераторы питания ТРАНСТЕКСТА… Чатрукьяну страшно не хотелось погружаться в этот мир, да и вставать на пути Стратмора было далеко не безопасно, но долг есть долг. Завтра они скажут мне спасибо, - подумал он, так и не решив, правильно ли поступает. Набрав полные легкие воздуха, Чатрукьян открыл металлический шкафчик старшего сотрудника лаборатории систем безопасности.

В шифровалке все в порядке! - Телефон не унимался. Джабба принялся устанавливать на место новый чип. Через минуту его усилия увенчались успехом, а телефон все звонил и звонил. Христа ради, Мидж. Ну хватит. Телефон заливался еще секунд пятнадцать и наконец замолк. Джабба облегченно вздохнул.

ГЛАВА 29 Все еще нервничая из-за столкновения с Хейлом, Сьюзан вглядывалась в стеклянную стену Третьего узла. В шифровалке не было ни души. Хейл замолк, уставившись в свой компьютер.
