2019-4-17 · If hot metal is allowed to cool slowly, the resulting grains are large, making a metal that is easy to shape. This process is known as annealing. When a hot metal is cooled quickly, the crystals produced are small. When this cooling is carried out in water, it is called quenching. Quenching will produce a metal that is strong, hard, and brittle.

Nonmetal - Wikipedia

2019-4-17 · In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals

Metalloid - Wikipedia

2019-4-17 · A metalloid is an element that possesses properties of both metals and non metals, and which is therefore hard to classify as either a metal or a nonmetal. This is a generic definition that draws on metalloid attributes consistently cited in the literature. Difficulty of egorisation is a key attribute.
