Some nonmetals (black P, S, and Se) are brittle solids at room temperature (although each of these also have malleable, pliable or ductile allotropes). From left to right in the periodic table, the nonmetals can be divided into the reactive nonmetals and the noble gases. The reactive nonmetals near the metalloids show some incipient metallic ...

A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Malleability, a similar mechanical property, is characterized by a material's ability to deform plastically without failure under compressive stress. [8] [9] Historically, materials were considered malleable if they were amenable to forming by hammering or rolling. [10] Lead is an example of a material which is relatively malleable but not ductile.
The important interaction between phosphate and magnesium ions makes magnesium essential to the basic nucleic acid chemistry of all cells of all known living organisms. More than 300 enzymes require magnesium ions for their catalytic action, including all enzymes using or synthesizing ATP and those that use other nucleotides to synthesize DNA ...
The theory describing the elastic fields of the defects was originally developed by Vito Volterra in 1907. [4] The term 'dislocation' referring to a defect on the atomic scale was coined by G. I. Taylor in 1934. [5] Prior to the 1930s, one of the enduring challenges of materials science was to explain plasticity in microscopic terms.
