Some reasons to reactivate a phone include dealing with lost or stolen property and deactivating a phone line. When a phone is lost or stolen, a consumers can deactivate their accounts with their service provider so that the thief can not use the phone. Once the phone is replaced, it will then have

The most reactive element is fluorine. It is never found in its free form in nature. Because it has seven electrons in its outer energy level, fluorine is always on the lookout to find a single electron to give it a more stable configuration.

A metal atom's aptitude to lose electrons to other atoms causes it to be more reactive. Involved in the scientifically determined aptitude is the speed at which a metal atom can lose electrons, as well as the substances with which the atom is likely to react.

Carbon reacts with oxygen. When burned, carbon produces carbon dioxide and carbon monoxide. Carbon does not react with water, acids or other chemical compounds, but carbon atoms can unite with oxygen and hydrogen atoms to form refrigerants, solvents, lubricants and fossil fuels. It is the basis of o

Reactivity in science refers to how various chemicals participate in chemical reactions when they are exposed to other substances. A chemical that reacts easily with other substances is considered highly reactive.

Reactive policing is a way of responding to citizens' needs for law enforcement rather than anticipating them. Traditional police forces use a form of reactive policing in respect to the fact that citizens must contact law enforcement with concerns or requests, and law enforcement officials then res
