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 proposed that atoms are indivisible and indestructible. The idea that atoms cannot be created or destroyed is one of its key postulates. The statement about a massive, positively - charged center is related to Rutherford's model, the idea of atoms being broken down into smaller pieces contradicts Dalton's initial view (he thought atoms were the smallest units), and the description of electrons in energy levels is part of the later quantum - mechanical model.

Answer:

Atoms cannot be created or destroyed.
