Which subatomic particles do not affect the stability of the atom?

• A. Protons
• B. Both protons and neutrons
• C. Neutrons
• D. Electrons

Answer: (D)

Verified step by step guidance

1. Understand the roles of subatomic particles in an atom: protons, neutrons, and electrons.
2. Recall that protons determine the identity of the element and contribute to the positive charge of the nucleus, affecting the atom's stability.
3. Recognize that neutrons contribute to the nuclear strong force that holds the nucleus together, thus playing a key role in nuclear stability.
4. Note that electrons orbit the nucleus and are involved in chemical reactions, but their presence or absence does not affect the nuclear stability of the atom.
5. Conclude that electrons do not affect the stability of the atom, while protons and neutrons do.
