Why is a complete atom considered to be electrically neutral?

• A. Because it has more electrons than protons.
• B. Because it has more neutrons than protons.
• C. Because it has an equal number of protons and electrons.
• D. Because it has an equal number of neutrons and electrons.

Answer: (C)

Verified step by step guidance

1. Understand that an atom is composed of three main subatomic particles: protons, neutrons, and electrons.
2. Protons are positively charged particles found in the nucleus of an atom, while electrons are negatively charged particles that orbit the nucleus.
3. Neutrons are neutral particles, also located in the nucleus, and do not contribute to the electrical charge of the atom.
4. An atom is considered electrically neutral when the total positive charge from the protons equals the total negative charge from the electrons.
5. Therefore, for an atom to be electrically neutral, it must have an equal number of protons and electrons, balancing the positive and negative charges.
