select all the correct answers. why do the atoms in a piece of copper metal have no net charge? the charges of the positive and negative copper ions cancel each other out. the number of electrons surrounding each copper nucleus doesn’t change. copper atoms can’t lose electrons without a substance present to gain electrons. when a copper atom loses electrons, it also loses a corresponding number of protons. the copper atoms exchange neutrons instead of electrons.

Answer

Brief Explanations:

Atoms are neutral when the number of protons (positive - charged) equals the number of electrons (negative - charged). In a piece of copper metal, copper atoms don't lose electrons without a substance to gain them, so the positive and negative charges remain balanced. Also, the number of electrons around each copper nucleus doesn't change under normal conditions in a pure copper piece.

Answer:

The number of electrons surrounding each copper nucleus doesn't change. Copper atoms can't lose electrons without a substance present to gain electrons.
