Metals Nonmetals and Metalloids TEKS 6 6a Compare

Metals, Nonmetals, and Metalloids TEKS 6. 6(a) Compare metals, nonmetals, and metalloids using physical properties such as luster, conductivity or malleability

Metals are elements that have certain properties generally characterized by ductility, malleability, luster and conductivity of heat and electricity. Luster: Shiny Conductivity: Yes both, Thermal and Electrical Aluminum Malleable: Yes

Non Metals- elements with properties opposite of metals. Nonmetal Luster: Diamonds is adamantine to waxy Graphite is metallic to dull. Conductivity: (most nonmetals are poor conductors) Diamonds are excellent sources of thermal conductivity and are excellent electrical insulators Graphite- good conductor of electricity Diamonds are one of the crystal forms of the element carbon and is one of the hardest. Malleable: Diamonds : No Graphite, one of the softest forms of carbon

Share properties of both metals and nonmetals, can be shiny or dull; somewhat malleable and ductile, semiconductor. Metalloids Luster: Metallic Conductivity: Will conduct thermal heat when a rise in temperature occurs. Malleable: No Germanium is a gray-white element with a metallic luster.
