Justify and tell why an atom is neutral though it has positively charged protons and negatively charged electrons

Atoms are electrically neutral because they contain equal quantities of positively charged protons and negatively charged electrons. Electrons and protons have equal but opposite charges, so the result is no net charge. Ions are atoms that have gained or lost electrons. As a result, ions have a net charge.

The correct answer is "false"
