Metals And Nonmetals Comparison Essay

Metals and Nonmetals

As shown on the periodic table of the elements below, the majority of the chemical elements in pure form are classified as metals. It seems appropriate to describe what is meant by "metal" in general terms. This general description is adapted from Shipman, et al.

  • Good electrical conductors and heat conductors.
  • Malleable - can be beaten into thin sheets.
  • Ductile - can be stretched into wire.
  • Possess metallic luster.
  • Opaque as thin sheet.
  • Solid at room temperature (except Hg).
  • Poor conductors of heat and electricity.
  • Brittle - if a solid.
  • Nonductile.
  • Do not possess metallic luster.
  • Transparent as a thin sheet.
  • Solids, liquids or gases at room temperature.

Metalloids are groups of elements in the periodic table that have properties between the metals and the non-metals which apparently cannot be or hardly classified as either metal or non-metal. The elements included in this group are Boron (B), Silicon (S), Germanium (Ge), Arsenic (As), Antimony (Sb) and Tellurium (Te). 

In comparison with metals*, metalloids are solid can be a conductor but in a fairly manner only. They also have higher densities compared to non-metals...

Metalloids are groups of elements in the periodic table that have properties between the metals and the non-metals which apparently cannot be or hardly classified as either metal or non-metal. The elements included in this group are Boron (B), Silicon (S), Germanium (Ge), Arsenic (As), Antimony (Sb) and Tellurium (Te). 

In comparison with metals*, metalloids are solid can be a conductor but in a fairly manner only. They also have higher densities compared to non-metals and have a metallic appearance. In contrast, metalloids are more brittle compared with metals which are ductile and malleable (if solid).

In comparison with non-metals, metalloids can be insulators and are brittle (if non-metals are in solid form). In contrast, non-metals are not as lustrous as metalloids and most of the non-metals are gasses.

Metalloids generally are located somewhere between metals and non-metals with electronegativity and ionization energy values.

*Some metals are liquid at or near room temperature (Hg, Fr, Ga, Cs).
