Column I

Alkali Metals

Column II

Alkaline Earth Metals

Metalloids

Be, Si, Ge, As, Sb, Te, Po, At

Transition Metals

Groups 3-12, 1-2 electrons in the outer energy level, less reactive than alsali-earth metals, shiny, good conductor of thermal energy and electrical current, high density

Column V

Pnictogens

Column VI

Chalcogens

Column VII

Halogens

Column VIII

Noble Gases

Metals

left of the zigzag line, shiny, malleable, ductile, good conductors of electric current, good conductors of thermal energy

Nonmetals

right of the zigzag line, not malleable/ductile, not shiny, poor conductors

Inner Transition Metals

an element in the lanthanide or actinide series; the highest occupied s sublevel and nearby f sublevel of its atoms generally contain electrons

Lanthanides

the first of the two rows below the main part of periodic table. usually used in alloys, soft, malleable, shiny and good electrical conductors

Actinides

in the 2nd row of transition metals, radioactive, unstable, do not occur in nature
