Seven elements in the metalloid family separate the metals from the nonmetals on the periodic table. Hydrogen is on the metal side of the metalloids, but is considered to be a nonmetal.
The staircase-shaped line is a typical example of the arbitrary metal–nonmetal dividing line found on some periodic tables. References This is the template sandbox page for Template:Periodic table (metalloid) (). Template documentation Usage Setting parameter
The elements can be classified as metals, nonmetals, or metalloids. Physical Properties of Metals Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
Metalloid, or semi metal, is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal.
