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. Atoms are neither created nor destroyed in chemical reactions. The idea of a massive, positively - charged center (nucleus) was part of Rutherford's model. The concept of atoms being breakable into smaller parts came later with the discovery of sub - atomic particles. The idea of electrons in energy levels outside the nucleus is part of the Bohr model and later quantum mechanical models.

Answer:

Atoms cannot be created or destroyed.
