creating an activity series of metals introduction: Alloy: An alloy is a mixture or metallic solid solution composed of two or more elements. Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The physical properties, such as density, reactivity. The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base, the matrix, or the solvent. The secondary constituents are often called solutes. If there is a mixture of only two types of atoms, not counting impurities, such as a copper-nickel alloy, then it is called a binary alloy. If there are three types of atoms forming the mixture, such as iron, nickel and chromium, then it is called a ternary alloy.
Solution: In chemistry, a solution is a homogeneous mixture composed of only one phase. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The solvent does the dissolving. The solution more or less takes on the characteristics of the solvent including its phase, and the solvent is commonly the major fraction of the mixture. The concentration of a solute in a solution is a measure of how much of that solute is dissolved in the solvent.
Metals: A metal is an element, compound, or alloy that is a good conductor of both electricity and heat. Metals are usually malleable, ductile and shiny. The meaning of the term "metal" differs for various communities. Many compounds that are not normally classified as metals, become metallic under high pressures. Metals typically consist of close-packed atoms, meaning that the atoms are arranged like closely-packed spheres. Metals in general have high electrical conductivity, high thermal conductivity, and high density. They typically are deformable under stress without cleaving. Some metals that have low density, low hardness, and low melting points, these (the alkali and alkaline earth metals). In terms of optical properties, metals are opaque, shiny, and lustrous. The majority of metals have higher densities than the majority of non-metals. Nonetheless, there is wide variation in the densities of metals. Lithium is the least dense solid element and osmium is the densest.
