alkali metalsSilvery solids with low densities and low melting points found in Group 1
alloyA mixture of two or more elements,one of which is a metal
ductile, Capable of being drawn out, as into wire or a thread.
atomic numberBasis for arranging elements in modern periodic table
actinidesRadioactive, unstable elements in transition metals
groupA vertical row of elements in the periodic table, elements in group share chemical properties, also called a family
halogensGroup of elements that form salt
hydrogenOnly nonmetal in group 1
lanthanidesSeries of elements that are sometimes called rare earth elements
malleableCapable of being shaped or bent or drawn out
metalsThey are shiny, ductile, malleable, good conductors of thermal energy
metalloidsHave characteristics of both metals and nonmetals
noble gasesThese elements do NOT react with any other elements.
nonmetalsNot malleable, not ductile, not shiny, poor conductors of thermal energy and electric current,
periodsHorizontal rows of periodic table; within period, elements near each other have similar properties
mass numberThe total number of protons and neutrons in an atom's nucleus
representative elementsA group in the periodic table which includes metals, metalloids, and nonmetals
semiconductorsElements that show moderate electrical conductivity
transition elementsElements in Groups 3-12 of the periodic table
