I am so sorry if this is a bit off topic, but it would kill me if i didn't correct you.
There are not 29 atoms in copper (Cu), because copper itself is an element and therefore takes the form of an atom.
The number 29 is somehwhat correct as copper has 29 protons, and it also has 34 neutrons and if neutral, 29 electrons. It is 63.546 atomic mass units.
Anyways, I love your work and you are a great contribution to this website.
