Elements
The elements,
alone or in
combinations,
make up our
bodies, our world,
our sun, and in
fact, the entire
universe.
Periodic Table
Whats in a square?
Different periodic
tables can include
various bits of
information, but
usually:
atomic number
symbol
atomic mass
number of valence
electrons
state of matter at room
temperature.
Atomic Number
Wave Model
Atomic Mass
The unit of
measurement for
an atom is an AMU.
It stands for atomic
mass unit.
One AMU is equal
to the mass of one
proton.
There are
6 X 1023 or
600,000,000,000,000,
000,000,000 amus in
one gram.
(Remember that
electrons are 2000
times smaller than one
amu).

Properties of Metalloids
Silicon
Metalloids (metal-like)
have properties of both
metals and non-metals.
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.

Transition Metals
Transition Elements
include those elements
in the B families.
These are the metals
you are probably most
familiar: copper, tin,
zinc, iron, nickel, gold,
and silver.
They are good
conductors of heat and
electricity.

Chlorine is an element.
When sodium and
chlorine bond they
make the compound

than the elements that make them up.
Table salt has different properties than
sodium, an explosive metal, and chlorine,
a poisonous gas.

Hydrogen is an element.
Oxygen is an element.
When hydrogen and
oxygen bond they make
the compound water.
When salt and water are
combined, a mixture is
created. Compounds in
mixtures retain their
individual properties.
