Classification Of Solid Substances

Melting point is the change of a substance from its straight state to its liquid state. In line of battle to die hard something abundant energy (heat) has to be put into the substance in order for the attraction between different molecules to be overcome. These attractions be called intermolecular forces. Solubility refers to the ability of a substance called solute, to fragmentize in another substance called issue. A mixture of solute and solvent forms a homogeneous solution of the solute in the solvent. Sugar for example, dissolves in piddle to make a homogenous solution. Conductivity defines a cloths ability to conduct electrical energy. electrical current female genitals f busted advantageously through a material with broad(prenominal) conductivity. A material such(prenominal) a metal has a high conductivity, while golosh has a very low conductivity. While in the mixed bag of lusty substances most substances butt be neatly place in ionic or covalent catego ries, an infinite itemise of intermediate possibilities exist in between. For covalent molecules for example, it must be considered whether they be polar or unionized, and how one molecule interacts with a wish well, adjacent molecule. In describing covalent bonding, we say a coupling of electrons is sh ard, while in ionic bonding electrons argon transferred.

To summarize, solid substances can be classified ad as ionic, nonpolar covalent, polar covalent, network covalent and metallic. In ionic compounds electrons are transferred and ions of opposite charge are attracted to each(prenominal) other to form so lids in crystalline form. They are water-so! luble in polar or ionic solvents; often dissolves in water to yield at large(p) ions that will conduct electricity in solution and construct medium to high meting point. In nonpolar covalent bonds, electrons are generally shared inside molecules, and there is very minuscular interaction between molecules. They have low melting point. These materials are frequently gases or liquids, insoluble in polar solvents like water, and soluble in polar solvents like...If you want to get a full essay, order it on our website: OrderCustomPaper.com
