Answer

Brief Explanations:

In a neutral atom, the number of protons (positively - charged) equals the number of electrons (negatively - charged). Copper atoms in a piece of metal are neutral. Copper atoms don't lose electrons without a substance to gain them. If they did, they'd become ions. But in the metal, they remain neutral as there's no electron - accepting substance present. Also, atoms don't lose protons during normal chemical or physical processes in a metal piece, and neutrons are not involved in charge - related processes for neutrality.

Answer:

C. Copper atoms can't lose electrons without a substance present to gain electrons.
