Structure of
Matter
•
•
Analyze what makes up matter
Compare the different models of an
atom.
Structure of Matter
Define
matter
anything that has
mass
_________
and takes
up space
Structure of Matter
What is
matter?
 air is matter
 water is matter
 most of the things
you see, taste,
smell, and touch are
made of matter
Structure of Matter
What isn’t
matter?
 light
 heat
 thoughts, feelings,
ideas
these things have no
mass, nor do they take
up space
Structure of Matter
What
makes up
matter?
atoms
Structure of Matter
Define
atom
a particle that makes
up most types of
___________
matter
Structure of Matter
created
Can matter matter is not _________
destroyed it just
be made or nor ___________,
destroyed? changes into a different
form this is the law of
conservation of matter
Structure of Matter
Before Lavoisier, people used
to think _________
matter
could
appear and disappear.
Structure of Matter
What was
Dalton’s
model of an
atom?
the atomic theory of
matter: each type of
matter was made of
only _________
one kind of
atom
Structure of Matter
How small
is an atom?
1 million lined up in a
row would be as thick
as a human hair
(too small to be seen
by a classroom
microscope)
Structure of Matter
What is an
electron?
invisible particles of
an atom with
negative charges
Structure of Matter
What was
Thomson’s
model of an
atom?
Thomson thought an
atom was a ball of
______________
positive charges
with negatively
charged electrons in
it
Structure of Matter
What was
Rutherford’s
model of an
atom?
Rutherford’s model
nucleus
included a ________
with protons inside
and electrons around
the nucleus
Structure of Matter
Define
nucleus
positively charged,
central part of an
atom
Structure of Matter
Define
proton
___________
positively
charged particles in
the nucleus of an
atom
Structure of Matter
How was
James Chadwick, a
the neutron student of Rutherford,
discovered? discovered neutral
particles that gave the
nucleus more mass
Structure of Matter
Define
neutron
neutral particle in the
nucleus of an atom
Structure of Matter
What was
Bohr’s
model of an
atom?
Bohr’s model indicated
that electrons traveled
in paths around the
nucleus
(lowest energy levels
closest to the nucleus)
Structure of Matter
Modern
Atomic
Model
Electrons travel in an
electron cloud rather
than in paths
