6.6C- Identify elements on the periodic table as metals, nonmetals, metalloids, and rare Earth elements based on their physical properties and importance to modern life

Rare Earth Metals

Metal

a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light.

Conductivity

A property that describes if heat or electrical charges pass through the material easily

Ductile

A property that describes the ability to be drawn into long, thin wire

Luster

A property that describes having a shiny appearance or reflecting light

Malleable

A property that describes the ability to be easily hammered and shaped

Shiny

glassy surface; reflecting light easily

rare earth Metals

A group of special metals from underground that are difficult to extract and process

Metalloid

a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal

Semi-Conductor

a material that can conduct electricity in some circumstances and block it in others, depending on its temperature

Nonmetals

a chemical element that mostly lacks distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine

Brittle

a material property that describes how easily something breaks or snaps when stressed

Dull

Lacking brightness; not having a shiny surface

Insulator

a material that is a poor conductor of electricity or heat

Periodic Table

An arrangement of the elements showing the repeating pattern of their properties.

Element

A substance that contains one kind of atom and cannot be broken down into a simpler form
