What particles are found in the
nucleus of the atom?
Protons and
Neutrons
they are help together
by the
STRONG FORCE
7
What particle is found surrounding
the nucleus?
What makes the atom neutral?
Protons =
Electrons
+ = -
( the charges, cancel each other out)

TO HELP ME FIND THE
NUMBER OF
SUBATOMIC
PARTICLES IN ANY
PARTICULAR ATOM, I
have to remember the
ACRONYM:

these 3
are the

Use the rest of the Class to
Draw the Atoms of the elements
on Atomic Structure I -III.
These will be used to create
your own Periodic Table this
week. Do them NEATLY and
remember to simplify.
