Why do the atoms in a piece of copper metal have no net charge?
Marat540 [252]

Answer;

-The charges of the positive and negative copper ions cancel each other out.

Explanation;

-A normal atom has a neutral charge with equal numbers of positive and negative particles.That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number.

-Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus anionic.
