Question & Answer Forum Next time you have a doubt while studying, you know where to go. Why do ionic compounds do not conduct electricity in solid state. But conduct electricity in molten state? What type of chlorides are formed by metals and what type of chlorides are formed by non-metals? (B) Why do metals form ionic chlorides are

Ionic Compounds - Chemistry | Socratic

Ionic compounds are compounds formed between a metal and nonmetal which have a crystalline lattice structure. They can conduct electricity and are usually highly water soluble. The ionic compounds can form one cohesive compound, such as Potassium Fluoride, or form more complex polyatomic ionic compounds, such as Calcium Carbonate.

Ruthenium - Element information, properties and uses

Ruthenium compounds also have some nice optical and electronic properties. Like its lighter close relative, iron, ruthenium readily forms a nuer of oxides including some exotic oxygen bridged multi metallic compounds. One such material, ruthenium red, is a dye used to stain negatively charged biomolecules such as nucleic acids in microscopy.

Gallium - Wikipedia

2019-4-29 · Gallium is a chemical element with syol Ga and atomic nuer 31. Elemental gallium is a soft, silvery blue metal at standard temperature and pressure; however in its liquid state it becomes silvery white.If too much force is applied Gallium may fracture conchoidally.It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium, and

Post-transition metal - WikiVisually

"All of the [Group 12] metals, but especially mercury, tend to form covalent rather than ionic compounds." The oxide of mercury in its preferred oxidation state (HgO; +2) is weakly amphoteric, as is the congener sulfide HgS. It forms anionic thiomercurates (such as Na …

Compounds Of Alkaline Earth Metals - Study Material …

Calcium fluoride or fluorospar (CaF 2) is by far the most important of all the fluorides of the alkaline earth metals since it is the only large scale source of fluorine. CaCl 2 is widely used for melting ice on roads, particularly in very cold countries because 30% eutectic mixture of CaCl2/ice freezes at 218 K as compared to NaCl /ice at 255K.

3 The chemistry of water - ScienceDirect

An important property of water is its ability to dissolve substances. There are only a few compounds known, which do not dissolve at least to some extent in water. The basic reason for the remarkable dissolving and ionization capability of water is its dipole character and the high dielectric constant.
