Classification Of Solid Substances

Melting point is the change of a substance from its simple state to its liquid state. In line of battle to dismiss something abundant energy (heat) has to be put into the substance in order for the attraction between different molecules to be overcome. These attractions ar called intermolecular forces. Solubility refers to the ability of a substance called solute, to dissolve in another substance called settlement. 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. voltaic current female genitals f busted soft through a material with broad(prenominal) conductivity. A material such(prenominal) a metal has a high conductivity, while preventative has a very low conductivity. While in the motley of good substances most substances butt be neatly position in ionic or covalent categories, an infinite come up of intermediate possibilities exist in between. For covalent molecules for example, it must be considered whether they atomic number 18 polar or unionized, and how one molecule interacts with a interchangeable, adjacent molecule. In describing covalent bonding, we say a coupling of electrons is sh ard, while in ionic bonding electrons are 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 solids in crystalline form. They are! water-soluble in polar or ionic solvents; often dissolves in water to yield bleak ions that will conduct electricity in solution and bushel medium to high meting point. In nonpolar covalent bonds, electrons are generally shared inside molecules, and there is very diminished 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
