Question

The following statements differentiate the Dalton and the Quantum atoms: 1. All atoms of an element are identical to each other 2. Subatomic particles make up the atoms 3. Compounds are formed when atoms combine with each other a. I, II and III b. II and III c. I and III d. I and II

Answer 1

Statements 1 and 3 are consistent with Dalton's Atomic Theory while Statement 2 is consistent with the Quantum mechanical model of atoms. Therefore, the correct answer to the student’s question would be option d (I and II).

Step-by-step explanation:

The statements differentiate the Dalton and Quantum models of atoms. Dalton's Atomic Theory, commonly known as Dalton's model, suggests that, 1. All atoms of an element are identical to each other, and 3. Compounds are formed when atoms combine with each other. The Quantum mechanical model goes beyond these ideas and includes 2. Subatomic particles make up the atoms. It gives a more accurate depiction of atom's structure where electrons exhibit wave-particle duality. Thus, the answer to the question is option d. I and II.
