What are Berthollide compounds?
Definition of berthollide : a solid chemical compound (such as some metallic hydrides and the tungsten bronzes) that does not conform to the law of definite proportions : a nonstoichiometric compound —distinguished from daltonide.
Is chlorine gas a compound or molecule?
Chlorine gas is the elemental form of the chemical element chlorine at standard temperature and pressure. Chlorine gas consists of molecules, rather than atoms of chlorine.
What group is chlorine in?
group 17
Chlorine is in group 17 of periodic table, also called the halogens, and is not found as the element in nature – only as a compound. The most common of these being salt, or sodium chloride, and the potassium compounds sylvite (or potassium chloride) and carnallite (potassium magnesium chloride hexahydrate).
What are stoichiometric and nonstoichiometric compounds?
Stoichiometric defects are those that do not disturb the stoichiometry of a compound. Nonstoichiometric defects are defects in crystal structures that disturb the stoichiometry of the crystal. Effect on Stoichiometry. They do not affect the stoichiometry of the compound. They change the stoichiometry of the compound.
What compounds can have non-stoichiometry?
13.1. 2 Classification. Most of the nonstoichiometric compounds are transition metal oxides, but also include fluorides, hydrides, carbides, nitrides, sulfides, tellurides, and so on [4,12,13]. The nonstoichiometric compounds existing only in the condensed state are often classified in terms of element composition.
What elements are in chlorine gas?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them….

Is chloride and chlorine same?
Chlorine: The greenish-yellow, highly reactive and diatomic gas that is almost never found free in nature by itself. Most Chlorine is commercially produced and is most widely known for being used within compounds to purify water and create cleaning products. Chloride: The negatively charged ionic form of Chlorine.
Is chloride a Cl or CI?
The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.

Is chlorine a salt?
If you remember those science classes from school, salt is made up of NaCl or sodium chloride. The salt system separates the two and generates natural chlorine. The two combine again back into salt for the process to repeat again.
