Which subatomic particle is primarily responsible for magnetic properties due to its intrinsic spin?

• A. Proton
• B. Alpha particle
• C. Electron
• D. Neutron

Answer: (C)

Verified step by step guidance

1. Understand that magnetic properties in atoms arise mainly from the intrinsic spin and magnetic moment of subatomic particles.
2. Recall that protons and neutrons are located in the nucleus, while electrons orbit the nucleus and have intrinsic spin contributing to magnetism.
3. Recognize that alpha particles are composed of two protons and two neutrons and do not individually contribute to magnetic properties in the same way electrons do.
4. Focus on the electron, which has a magnetic moment due to its spin and orbital motion, making it the primary source of magnetic behavior in materials.
5. Conclude that the electron's intrinsic spin is the key factor responsible for magnetic properties, distinguishing it from protons, neutrons, and alpha particles.
