Explanation:
The atomic number of Copper is 29. So immediately we know that there are <em>29 protons </em>in the nucleus of each Copper atom, and <em>29 electrons</em> in the cloud surrounding the nucleus of each [neutral] Copper atom.
Copper has two stable isotopes ... ⁶³Copper and ⁶⁵Copper. So if the Copper atom you're holding in your hand is not radioactive, then it has either (63-29)=<em>34 neutrons</em> or (65-29)=<em>36 neutrons</em> in its nucleus. (There's never a need to round the number of neutrons, because there's no such thing as a <em>part </em>of a neutron.)
