General chemical properties of Metals. The chemistry of metals is studied by analysing their reactions with water, dilute acid and oxygen. Based on these reactions a reactivity series of metals can be produced. Reactivity with water. Some metals react with water, either warm or cold, or with steam.
Alloys are metal compounds made by combining a metal with other elements. This process is carried out to give the material greater strength or resistance to corrosion. Examples of alloys: Brass is a mixture of copper and zinc. Stainless steel is a mixture of iron and other elements like chromium, nickel and carbon.
Kitchen sinks, cutlery, surgical instruments. Due to the irregularity in atom sizes and structure, metal alloys, which stop layers from sliding over each other, are stronger. This is what the structure of an alloy (a) looks like compared to a pure metal (b).

Chemical Properties. When metals react with oxygen, they tend to form metal oxides in a corrosion process. Most metals react with acids to produce a salt and hydrogen gas. Metals tend to lose electrons in chemical reactions, this ability to donate electrons makes them good reducing agents.
