negatively charged particle that orbits the center of an atom

group

term for the columns of the periodic table also known as families

proton

positively charged particle in the nucleus of the atom

metal

elements that are good conductors of electricity and heat often shiny and bendable

luster

shiny and reflective

malleable

can be hammered or rolled into flat sheets or shapes

ductile

can pulled out or drawn into long wires

thermal conductivity

ability to transfer heat

electrical conductivity

ability to carry electrical current

reactivity

ease and speed with which one element combines with another

corrosion

deterioration of a metal due to a chemical reaction

alkali metals

most reactive elements, are seldom found uncombined with other atoms

alkaline earth metals

these metals are harder and denser and melt at higher temperatures

nonmetal

element that lacks most properties of a metal. mostly found on the right side of periodic table

diatomic molecule

two molecules of the nitrogen family are combined with each other and is not very reactive

halogens

means "salt forming" flourine, bromine, chlorine and iodine. very reactive

noble gasses

elements of group 18. Do not normally form compounds because they do not share electrons

metalloids

have some properties of metals and some of nonmetals. Solid at room temperature. Hard Brittle and somewhat reactive

semiconductors

substances that can conduct electricity under some conditions
