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.Know More
Metals belong to one of four classes depending on their reactivity potential, with the first class containing the most reactive metals. When metal atoms react with and lose electrons to water, oxygen or an acid, it tarnishes or corrodes, producing positive and negative ions. Metals that react with water or oxygen, found within the first class of reactive metals, are more reactive than those that need an acid to undergo a chemical reaction.
The strength of the acid needed by a metal to produce a chemical reaction determines its level of reactivity. For example, copper demands an acid strong enough to oxidize its atoms and therefore resides in the third class. On the other hand, aluminum, which rapidly reacts with less potent acids, belongs to the second class.
One way to predict a metal's ability to react is by examining the electron structure of its atoms compared to the electron structure of its reactant. The valence electrons, those found in the outermost shell of an atom, determine the atom's degree of electronegativity. Metal atoms with lower electronegativity lose valence electrons more easily and consequentially qualify as more reactive. These atoms are capable of greater reactivity because they combine readily with the atoms in water and oxygen, which possess high degrees of electronegativity.Learn more about Chemistry
According to Encyclopedia Britannica, silver is one of the least types of chemically reactive elements. Silver is a chemical element, and the metal is a lustrous and white color.Full Answer >
Arsenic is not particularly reactive though yellow arsenic is the most reactive and reacts with halogens under controlled conditions, fluorine and slowly with air (oxidization only). Arsenic does not react with water and is not explosive.Full Answer >
Fluorine is the most reactive of the halogens because it is at the top of the halogen group, which is the second to right group on the periodic table. With halogens, the higher an element is in the column, the more reactive it is.Full Answer >
A reactive hepatitis B surface antigen, or HBsAg, result means that the hepatitis B virus is present and the person is infected. According to the Hepatitis B Foundation, the infection can either be acute or chronic and those individuals infected with the virus can pass it to other people.Full Answer >
