Answer 1

John Dalton's atomic theory includes fixed ratios of atoms in compounds, different atoms for different elements, and indivisible atoms.

Step-by-step explanation:

One of the components of John Dalton's atomic theory is that the ratio of atoms in a compound is fixed. This means that the elements in a specific compound will always combine in a certain ratio. For example, water always consists of two hydrogen atoms and one oxygen atom, giving it a fixed ratio of 2:1.

Another component of Dalton's theory is that the atoms of different elements are not the same. Each element has its own unique atoms with different properties. For instance, carbon atoms and oxygen atoms are different in terms of their atomic structure and properties.

Dalton's theory also states that an atom is a small particle of matter that cannot be broken down into smaller particles without losing its essential characteristics. Atoms are the building blocks of matter and are indivisible.
