Whois & Analysis for valencehealth.com

In chemistry, the valence or valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.

The concept of valence was developed in the second half of the 19th century and was successful in explaining the molecular structure of inorganic and organic compounds.

Health care or healthcare is the maintenance or improvement of health via the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in human beings.

Healthcare is delivered by health professionals (providers or practitioners) in allied health professions, chiropractic, physicians, physician associates, dentistry, midwifery, nursing, medicine, optometry, pharmacy, psychology, and other health professions.

A market is one of the many varieties of systems, institutions, procedures, social relations and infrastructures whereby parties engage in exchange.

While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services (including labor) in exchange for money from buyers.

It can be said that a market is the process by which the prices of goods and services are established.

Markets facilitate trade and enable the distribution and allocation of resources in a society.

Markets allow any trade-able item to be evaluated and priced.

A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights (cf.

ownership) of services and goods.

Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, source of goods for sale (local produce or stock registration), and the threat of military or police force if these rules are broken.

In chemistry, a solution is a homogeneous mixture composed of two or more substances.

In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

The mixing process of a solution happens at a scale where the effects of chemical polarity are involved, resulting in interactions that are specific to solvation.

The solution assumes the characteristics of the solvent (i.e., its phase) when the solvent is the larger fraction of the mixture, as is commonly the case.

The concentration of a solute in a solution is the mass of that solute expressed as a percentage of the mass of the whole solution.
