One strength of the explanation is that an atom's
mass consists mostly of the mass of its protons
and neutrons. Electrons have very little mass.
So, the atom must have lost either a proton or
neutron.
One weakness, however, is that neutrons have
no charge. So, removing the neutron should
not affect the atom's charge. It is more likely
that a proton was removed.
Draw the Diagram
–Identify the four parts of the atom that are pointed out by
arrows in the diagram above.
–Describe the electrical charges of the structures that are

The atom has a mass number of 13
• To find the mass number we have to know
the # of protons & the # of neutrons.
– We know there are 7 neutrons; ??? protons
• An atom with a charge of -1 has gained an
electron (added a – charge)
• Atoms begin w/ = numbers of protons &
electrons, so the atom began with 6
electrons & 6 protons.
• 6 protons + 7 neutrons =
• a mass # of 13
