Metals are generally good electrical conductors and good conductors of heat. They are malleable (can be beaten into this sheets) and ductile (can be stretched into thin wires). Most are shiny because the surface electrons are good reflectors of light. Examples are copper, gold, iron and chromium. The vast majority of pure elements in the periodic table are metals.
Most non-metals form individual molecules instead of extended solids and are poor conductors of heat and electricity. Examples are oxygen, nitrogen, argon and bromine. Most of the non-metal elements are clustered in the upper-right corner of the periodic table.
