The Periodic Table of Elements
ElementsElements are a PUREsubstance that cannot bebroken into simplersubstances. The elements, alone or incombinations (COMPOUNDS),make up our bodies, ourworld, our sun, and in fact, theentire universe.
Metals
Periodic Table
Metals appear to the left of the dark ziz-zag line on the periodic table.
Properties of Metals
Metals have
luster. This means they are
shiny
Properties of Metals
Ductilemetals can be pulled into a thin wire.
Properties of Metals
Malleablemetals can be hammered/ pounded into sheets
Properties of Metals
Metals have a high melting & boiling points.
Properties of Metals
Conductors Metals are
good conductors of electricity and heat
Properties of Metals
A chemical property of metal is its reaction with water and oxygen. This results in corrosion and rust.
Nonmetals
Properties of Nonmetals
Nonmetals occur to the right of the dark zig-zag on the periodic table. Although Hydrogen is on the left, it is also a nonmetal because of its physical and chemical properties .
Properties of Nonmetals
Nonmetals do not have luster; they are dull.
Properties of Nonmetals
BrittleNonmetals are
brittle so they break easily. This means nonmetals ARE NOT ductile or malleable.
Properties of Nonmetals
Many nonmetals are gases at room temperature.
Properties of Nonmetals
They also have a low melting point. This is why they are poor conductors of heat and electricity.
Metalloids
Properties of Metalloids
Metalloids can be found clustered around the
dark zig-zag line that separates metals
and nonmetals.
Properties of Metalloids
Metalloids (metal-like) have properties of both
metals and
nonmetals.
Properties of Metalloids
Metalloids are solids that can be
shiny or
dull.
Properties of Metalloids
They conduct
electricity and heat better than nonmetals but not as well as
metals.
Properties of Metalloids
Metalloids can
malleable or
ductile.
