Electrorefining Copper

anode reaction:Cu(s)→

cathode reaction:Cu2+(aq)+ 2e -→

overall reaction:Cu(s) + Cu2+(aq)→

Note that the concentration of copper ions in the electrolyte remains constant. For every copper ion produced at the cathode, a copper ion is reduced to metallic copper at the cathode.

i can ! i just need to know what the paragraph is! : p

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
