Metals, Metalloids and Nonmetals

Metals, Nonmetals and Metalloids

Periodic table is divided into three basic categories.

Metals, Nonmetals and Metalloids

Metals, Nonmetals and Metalloids

Multiple Choice

Which elements are found on the right side of The Periodic Table?

• metals

• nonmetals

• metalloids

Multiple Choice

All of the following would classify an element as a metal except?

• malleable

• ductile

• hard

• dull

Multiple Choice

Non-metals are good conductors of heat and electricity.

• true

• false

Metal Properties

• usually solid at room temperature (mercury is an exception)

• high luster (shiny)

• metallic appearance

• good conductors of heat and electricity

• malleable (can be bent and pounded into thin sheets)

Metal Properties Continuation

• ductile (can be drawn into wire)

• corrode or oxidize in air and sea water

• usually dense (exceptions include lithium, potassium, and sodium)

• may have very high melting point

• readily lose electrons

  
  

Metalloids or Semimetals

• have some of the properties of metals and some nonmetallic characteristics

• dull or shiny

• usually conduct heat and electricity, though not as well as metals

• often make good semiconductors

  
  

Metalloids or Semimetals

• often exist in several forms

• often ductile

• often malleable

• may gain or lose electrons in reactions
