The number of neutrons in 24Mg are? 2. Which of the following statements concerning the nucleus of an atom is correct? 3. Which of the following molecules is diatomic? 4. Which of the following statements is false? 5. Which of the following molecules is a molecule of elements?
Understand the Problem
The questions are part of a science quiz focused on atomic structure and molecular chemistry, specifically related to neutrons, atomic nucleus, and molecular types.
Answer
1) 12 neutrons, 2) D (Accounts for most volume), 3) A (O2), 4) B (Nucleus), 5) C (H2)
The answers are: 1) 12, 2) D, 3) A, 4) B, 5) C.
Answer for screen readers
The answers are: 1) 12, 2) D, 3) A, 4) B, 5) C.
More Information
The mass number of 24Mg is 24, and the atomic number is 12, so the number of neutrons is 24 - 12 = 12.
Tips
A common mistake is confusing diatomic molecules with simple elements. Remember diatomic molecules contain two atoms.
