Which statement belongs to Datton's 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

## Step 1<br />Dalton's atomic theory, proposed by John Dalton in the early 19th century, is a fundamental concept in chemistry. It consists of several postulates, including the idea that atoms cannot be created or destroyed in chemical reactions. This postulate is reflected in the statement "Atoms cannot be created or destroyed."<br /><br />## StepThe other statements provided in the question refer to different aspects of atomic structure and behavior that were discovered or theorized after Dalton's time. For instance, the concept of atoms having a massive positively charged center (the nucleus) and electrons located in energy levels outside of the nucleus are part of the nuclear model of the atom, which was developed later by Ernest Rutherford.<br /><br />## Step 3<br />Similarly, the idea that atoms can be broken down into smaller pieces is related to the discovery of subatomic particles, which also came after Dalton's atomic theory.
