What is the chemical composition of copper? Need ASAP thanks
Chemical composition of something is the elements that make up that something. copper itself is an element, and so 'chemical composition' of copper doesn't really make sense. Did you mean to say what is the electron configuration of copper ? if so, electrons per shell is 2, then 8, then 8, then 18, then 33 'first, second, third, fourth, and fifth shells'. Atomic number of copper is 29, so there are 29 electrons total, and 29 protons, the number of neutrons is copper's atomic weight minus the number of protons.
