Types of elements & Families

Types of Elements Metals Nonmetals Metalloids

Metals Most elements are metals!

Physical Properties of Metals Luster (shinniness) Good conductors of heat and electricity High density (heavy for their size) High melting point Ductile (can be drawn into thin wires) Malleable (hammered into thin sheets)

Chemical Properties of Metals: Easily LOSE electrons Corrode easily (tarnishing/rusting)

Nonmetals Found to the right of the staircase

Physical Properties No luster (dull appearance) Poor conductor of heat and electricity (except for Carbon) Brittle (breaks easily) Not ductile Not malleable Low density Low melting point

Chemical Properties of Nonmetals: Tend to GAIN electrond

Metalloids Elements on both sides of the staircase!

Physical Properties Solids Can be shiny or dull Ductile Malleable Conduct heat and electricity better than nonmetals but not as well as metals

Chemical Properties Tend to LOSE their electrons

Color/label your periodic table!

Create a Venn Diagram for Metals, nonmetals, and metalloids

Families Group 1a: Alkali metals Group 2a: Alkaline earth metals Transition metals Halogens Noble gases
