Metals, Nonmetals, and Metalloids

elements that have the characteristics of both metals and nonmetals

• alloy

• metalloid

• silicon

• corrosion

group of elements that has 7 valence electrons, is very reactive, and most of which are dangerous to humuns

• oxygen family

• nitrogen family

• noble gases

• halogen family

elements in Group 1; they are the most reactive and never found as elements, only as compounds in nature

• alkaline earth metal

• alkali metal

• alloy

• transition metal

a rare group of elements, most of which are lab created

• actinide

• lanthinide

• alkaline

• fluoride

elements located to the right of the stair in the periodic table; they are dull, brittle, and are poor conductors

• metalloid

• metal

• lanthanide

• nonmetal

describes a material's ability to be pounded or moved into shapes

• ductile

• magnetic

• malleable

• conductive

the quality of a material's shininess

• luster

• conductivity

• hardness

• malleability

the gradual wearing away of a metal element due to a chemical reaction

• conductivity

• corrosion

• alkalinity

• magnetism

a substance that can transfer electric current under some conditions

• conductor

• magnetic

• semiconductor

• transitional

a group of electrons with only 2 valence electrons, is fairly hard, and are good conductors

• alkali metals

• transition metals

• alkaline earth metals

• alloys
