1-8: Summary of Part 1 |
|
Let us summarize
what we have
learned in Part 1.
|
|
(1) |
If we divide
matter into finer
and finer portions,
we reach
atoms and
molecules.
Originally,
they were
considered to be
the minimum constituents
of the matter.
|
|
|
(2) |
It has been clarified
that there exists
a minimum element
of electric charge,
i.e. the
elementary charge
e.
|
|
|
(3) |
Moreover, there exists
an electron
which is much lighter
than the atoms.
It has also been
clarified that
the electron possesses
a negative charge -e.
|
|
|
(4) |
It has become
clear that
the electron
is one of the common
constituents
of atoms.
|
|
People understand
that both matter
and electricity
are not continuous
but consist of collections
of the fundamental quantities.
Let us call this
the atomic nature of
matter
and electricity.
