Q.2.30 P - Chemistry: Molecular Nature Of Matter And Change

Question

Which of Dalton’s postulates about atoms are inconsistent with later observations? Do these inconsistencies mean that Dayton was wrong? Is Dalton’s model still useful? Explain.

Step-by-Step Solution

Answer

Based on the above limitations, it can conclude that Dalton’s Postulates are still very useful and therefore they affirm and which further explain the mass of laws.

Dalton’s theory states that if atoms have the same size and mass, thus in this case we can conclude that it does not account for isotopes.

Step1. Limitations of Dalton’s postulates:

The limitations of Dalton’s postulate are as follows:

1. Dalton has not predicted the existence of subatomic particles.
2. The postulates were not able to explain the bond formation
3. Isotopes neglect the postulate which states that all atoms of an element have the same mass.

Step2. Observation from Daltons postulates:

Based on the above limitations, it can conclude that Dalton’s Postulates are still very useful and therefore they affirm and which further explain the mass of laws.

Dalton’s theory states that if atoms have the same size and mass, thus in this case we can conclude that it does not account for isotopes.
