Which of the following statements about electrons is NOT true?

• A. Electrons are involved in chemical bonding.
• B. Electrons are found in the nucleus of an atom.
• C. Electrons have a negative charge.
• D. Electrons have much less mass than protons.

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the role and properties of electrons in an atom. Electrons are subatomic particles with a negative charge and are much lighter than protons.
2. Step 2: Recall the structure of an atom: the nucleus contains protons and neutrons, while electrons are found in regions called electron clouds or orbitals surrounding the nucleus.
3. Step 3: Analyze each statement: (a) Electrons are involved in chemical bonding — this is true because chemical bonds form through interactions of electrons between atoms.
4. Step 4: (b) Electrons are found in the nucleus of an atom — this is false because electrons are located outside the nucleus, not inside it.
5. Step 5: (c) Electrons have a negative charge and (d) Electrons have much less mass than protons — both are true statements based on fundamental atomic theory.
