Dalton’s Atomic Theory was given by John Dalton.
According to this theory: -
(a) Matter is made up of invisible particles known as atoms.
(b) The properties of all the atoms of a given element are the same including mass.
(c) Atoms of different elements combine in fixed ratios to form compounds.
(d) Atoms are neither created nor destroyed.
(e) The formation of new products results from the rearrangements of existing atoms.
(f) Atoms of an element are identical in mass, size and properties.

Dalton's Atomic Theory
Dalton's atomic theory, proposed by John Dalton in the early 19th century, laid the foundation for modern atomic theory. It consisted of several postulates that described the nature of atoms and their behavior. While most of Dalton's postulates still hold true, there is one statement in the given options that is not in accordance with his atomic theory.
Statement b) Atoms can be divided into protons, neutrons, and electrons
This statement is not in accordance with Dalton's atomic theory because it suggests that atoms can be further divided into subatomic particles, namely protons, neutrons, and electrons. However, according to Dalton's theory, atoms are indivisible and indestructible particles.
Dalton's Atomic Theory Postulates
To understand why statement b) is not in accordance with Dalton's atomic theory, let's briefly review the postulates of his theory:
1. All matter is made up of very tiny particles called atoms: This postulate states that atoms are the building blocks of matter and cannot be further divided into smaller particles.
2. Atoms of a given element are identical in mass and chemical properties: According to Dalton, all atoms of the same element have the same mass and exhibit similar chemical properties.
3. Atoms combine in the ratio of small whole numbers to form compounds: Dalton observed that elements combine with each other in simple whole number ratios to form compounds. This postulate forms the basis for the concept of chemical formulas.
4. Chemical reactions involve the rearrangement of atoms: Dalton proposed that during a chemical reaction, atoms are rearranged to form new compounds, but no atoms are created or destroyed.
Explanation of the Incorrect Statement
The statement b) suggests that atoms can be divided into subatomic particles such as protons, neutrons, and electrons. However, modern scientific discoveries have shown that atoms are not indivisible and can indeed be further divided into these subatomic particles.
Conclusion
In conclusion, statement b) is not in accordance with Dalton's atomic theory, which postulates that atoms are indivisible and cannot be further divided into protons, neutrons, and electrons. This statement contradicts the understanding of atomic structure that has been developed since Dalton's time.
