Question

which statement belongs to daltons atomic theory? atoms have a massive, positively charged center. atoms cannot be created or destroyed. atoms can be broken down into smaller pieces. electrons are located in energy levels outside of the nucleus.

Explanation:

Dalton's atomic theory states that atoms are indivisible and indestructible, meaning they cannot be created or destroyed in a chemical reaction. The statement "Atoms cannot be created or destroyed" aligns with this theory. The other options are from later atomic models (e.g., the idea of a nucleus with a massive, positively - charged center is from Rutherford's model, and electrons in energy levels is a more modern concept).

Answer:

Atoms cannot be created or destroyed.
