Which of the following statements about subatomic particles is false?

• A. Electrons have a mass nearly equal to that of protons.
• B. Electrons are found outside the nucleus in regions called orbitals.
• C. Neutrons have no electrical charge and are located in the nucleus.
• D. Protons have a positive charge and are found in the nucleus of an atom.

Answer: (A)

Verified step by step guidance

1. Review the basic properties of subatomic particles: protons, neutrons, and electrons.
2. Recall that protons have a positive charge and are located in the nucleus of an atom.
3. Remember that neutrons have no electrical charge (they are neutral) and are also located in the nucleus.
4. Understand that electrons have a negative charge and are found outside the nucleus in regions called orbitals.
5. Compare the masses of electrons and protons: electrons have a much smaller mass than protons, so the statement that electrons have a mass nearly equal to that of protons is false.
