In a similar way‚ matter has properties and there are many of them. The two basic properties we associate with matter are physical and chemical properties. Physical properties are those properties that do not change the chemical nature of matter. Chemical properties are those properties that do change the chemical nature of matter. All physical and chemical properties observed for a compound are directly related to the compound’s molecular structure. The most common physical properties are

Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms

not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results in a polar bond. If the atoms have a similar or close to similar amounts of electronegativity‚ the compound is nonpolar. When two compounds that have different polarities are put in a situation together‚ they

properties are properties that can be measured and seen in an object. An example of a physical property of an object would be the color‚ mass‚ solubility‚ volume‚ or the polarity of an object. A physical property can change the appearance of an object‚ but that does not mean that the chemical composition has to change. The chemical composition can remain the same. Physical properties are separated into two different categories. They are separated in to intrinsic properties and extrinsic properties

Doe 07 Polarity Management Dr. Polarity Management Polarity Management is by definition a "problem" or an issue that requires a solution. The goal of a problem is to find a fix to the current situation and move forward to a new reality without being required to ever look back. However‚ a "polarity" is an issue that needs to be addressed‚ but the "solution" is not one that can survive independently and will actually still require support from the original issue. Polarity Management can
