Best Answer: The atomic number of copper is 29. The atomic number is the number of electrons and protons. The number of electrons and protons are always the same in an element. Copper has 29 electrons.
Copper is a metal that consists of a lattice of atoms, and you can imagine it like so: In 1 cm^3 piece of copper, there are about 10^23 of those little blue balls we call atoms. In each of those atoms, there are outer shells where electrons flow freely and, when bonded together with other atoms, join the free electrons of the other atoms. What we get is a so-called sea of electrons that flow from atom to atom, and it is precisely this that makes the copper conductive.
