Metals, Nonmetals, Metalloids - Montgomery County Schools

Metals, Nonmetals, Metalloids The elements of the periodic table can be divided into three main categories: Metals, Non-Metals, and Metalloids. Properties of Metals Metals are good conductors of heat and electricity. Metals are shiny. Metals are ductile (can be stretched into thin wires). Metals are malleable (can be

pounded into thin sheets). A chemical property of metal is its reaction with water which results in corrosion. Properties of Non-Metals Non-metals are poor conductors of heat and electricity. Non-metals are not ductile or malleable. Solid non-metals are

brittle and break easily. They are dull. Many non-metals are gases. Sulfur Properties of Metalloids Metalloids (metal-like) have properties of both metals and non-metals. They are solids that can be

shiny or dull. They conduct heat and electricity better than nonmetals but not as well as metals. They are ductile and malleable. Silicon 1. The Periodic table can be divided into what three categories A.
