What makes an Atom?
An ATOM is the smallest
piece of an element that exist.

in a straight line would be
about 1mm long.”

What is the Difference between
an Atom and an Ion?
An ATOM has the same number of
protons and electrons.
An atom has no overall electric charge.
If an atom loses or gains electrons
it is no longer called an atom.
It is called an ion.
What is the Difference between
an Atom and an Ion?
an ION
An ion has a full outer shell
of electrons.
An ion is either
positive or negative
because it has
an electric charge.
