['Metals are generally shiny, malleable, and hard. Metals are also good conductors of electricity. ... ', 'Non-metals do not conduct heat or electricity very well. Non-metals are typically brittle and are not easily molded into shapes. ... ', 'Metalloids share characteristics of both metals and non-metals and are also called semimetals.']

Typical metalloids have a metallic appearance, but they are brittle and only fair conductors of electricity. Chemically, they behave mostly as nonmetals. They can form alloys with metals. Most of their other physical properties and chemical properties are intermediate in nature.

The elements can also be divided into two main groups, the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties. There are some elements that show some, but not all, of the metallic properties.

Metals are dense, shiny, good conductors of heat and electricity, and easily lose electrons in chemical reactions. Nonmetals are not dense, dull, do not conduct heat and electricity, and tend to gain electrons. Metalloids are elements that have properties of both metals and nonmetals.

Unlike metals, non-metals are poor conductors of heat and electricity. They are brittle and usually dull in color. They sound boring, but they're actually the coolest. Carbon (C, Z = 6) is one of the least boring elements on the periodic table.

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).

Non-Ferrous Metals. Nonferrous metals offer a wide variety of mechanical properties and material characteristics. Nonferrous metals are specified for structural applications requiring reduced weight, higher strength, nonmagnetic properties, higher melting points, or resistance to chemical and atmospheric corrosion.

Metalloids are unique because they have properties of both metals and non-metals. ... Most metals have a characteristic lustre and are good conductors of heat and electricity. Most metalloids have a metallic lustre but are poor conductors of heat and electricity.

Metalloids are those elements which posses the properties of both metals and non metals. There can be 3,4,5,6 valence electrons in metalloids they are placed in the right side of the periodic table. They generally form amphoteric oxides .

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. ... They gain or share electrons when they react with other elements and chemical compounds.

Their melting and boiling points are generally lower than normal metals. Their electronegativity and conductivity is also higher, but their texture is softer than usual metals. These elements are distinguished from metalloids by their high boiling points compared to that row of elements in the periodic table.

Properties. Metalloids usually look like metals but behave largely like nonmetals. Physically, they are shiny, brittle solids with intermediate to relatively good electrical conductivity and the electronic band structure of a semimetal or semiconductor.
