Why are atoms considered neutral?

• A. They have equal numbers of neutrons and electrons
• B. The numbers of electrons and protons are equal
• C. They contain no particles
• D. They have more neutrons than protons

Answer: (B)

Atoms are considered neutral because they have equal numbers of electrons and protons. In an atom, protons carry a positive charge, while electrons carry a negative charge. When the number of protons equals the number of electrons, the positive and negative charges balance each other out, resulting in a neutral overall charge. This balance is fundamental to the structure of atoms. If there were an unequal number of protons and electrons, the atom would have a net electric charge, making it either positively or negatively charged, which is not the case in a neutral atom. Other options do not accurately describe the reason for an atom’s neutrality. The idea of equal numbers of neutrons and electrons does not affect charge neutrality since neutrons are uncharged. Additionally, stating that atoms contain no particles is incorrect, as atoms are made up of protons, neutrons, and electrons. Lastly, having more neutrons than protons would not result in neutrality; rather, it could lead to variations in atomic mass but not in charge.
