Metals, Nonmetals, & Metalloids

Periodic Table of Elements:

Metals, Nonmetals, & Metalloids

Metals, Nonmetals, Metalloids

There is a zig-zag or staircase line that divides the table.

Metalloids are on either side of the staircase, in purple.

Metals are on the left of the line, in blue.

Nonmetals are on the right of the line, in green.

Properties of Metals

•Good conductors of heat and electricity.

•Luster: shiny

•Ductile: can be stretched into thin wires

•Malleable: can be pounded into thin
sheets

•A chemical property of metal is its
reaction with water which results in
corrosion.

•

Location: 2/3 of all elements
▫left of the ladder
▫most active: lower left (Fr)

•

Lose/gain e-: lose electrons to form positive ions

Metals

Multiple Choice

Copper is used as wiring in many homes because it is a _________ metal.

• malleable

• ductile

• conductive

• insulated

Properties of NonMetals

• Poor conductors of heat
and electricity.

• Not ductile or malleable.

• Solid nonmetals are brittle

and break easily.

• They are dull.

• Many are gases.

Multiple Choice

Neon is colorless, a poor conductor of heat and is not able to be stretched. How would it be classified?

• metal

• nonmetal

• metalloid

• transition metal

Properties of Metalloids

• Metalloids (metal-like) have
properties of both metals and
nonmetals.

• They are solids that can be shiny or
dull.

• They conduct heat and electricity better than nonmetals but not as well as metals.

• They are ductile and malleable.

Metalloids (semimetals)

• Location: along the ladder
▫ 7 of them (B, Si, Ge, As, Sb, Te, and Po)

• Lose/gain e-: lose, gain or share electrons depending upon what it bonds to.

• Can form either positive or negative ions.

• Aluminum (Al) and Astatine (At) are disputed.

Multiple Choice

Aluminum is an element that is used to make soda cans and sheet metal for airplanes. What property of aluminum makes it useful in this way?

• Aluminum is a conductor

• Aluminum is ductile

• Aluminum is malleable

• Aluminum has a high melting point
