WebAn atom of copper has 29 electrons. Twenty-eight of them are stuck firmly in the atom, but one of them can move around freely. This free electron jumps around, and can switch places with other free electrons, circling around other atoms of copper in the wire. And these free electrons make copper capable of conducting electric current. WebThe copper atom, shown above, has 29 protons in its nucleus and 29 electrons orbiting its nucleus. As can be seen from the copper atom diagram, the electrons are arranged in 4 …
