Which of the following statements correctly describes a similarity and a difference between electrons and protons?

• A. Both electrons and protons are found in the nucleus, but electrons are heavier than protons.
• B. Electrons and protons have the same charge, but electrons are located outside the nucleus.
• C. Both electrons and protons are subatomic particles, but electrons have a negative charge while protons have a positive charge.
• D. Electrons and protons are both positively charged, but protons are found outside the nucleus.

Answer: (C)

Verified step by step guidance

1. Step 1: Identify the nature of electrons and protons as subatomic particles that make up atoms.
2. Step 2: Recall that electrons have a negative charge, while protons have a positive charge, which is a fundamental difference between them.
3. Step 3: Understand that both electrons and protons are subatomic particles, which is a similarity they share.
4. Step 4: Recognize the location difference: protons are found in the nucleus of an atom, whereas electrons are located outside the nucleus in electron clouds or orbitals.
5. Step 5: Evaluate each statement based on these facts to determine which correctly describes both a similarity and a difference between electrons and protons.
