Structure of the Atom ) Factoid
The diameter of the average atom is
only one tenth of one billionth of one
meter, but these tiny atoms are the
building blocks of everything. Atoms are
made of electrons, protons, and
neutrons, and they are held together by
the charges that the protons and
electrons carry: each proton carries a
positive charge and each electron carries
a negative charge. The total charge of
an atom is the sum of the charges from
its electrons and protons, and the total
charge of a molecule is the sum of the
total charges of the atoms making up
the molecule.
