The most accurately represented John Dalton's model of the atom is: C. a tiny, solid sphere with a predictable mass for a given element
<h3>Further explanation</h3>The development of atomic theory starts from the first term conveyed by Greek scientists who suggested that every substance has the smallest particles so that the word atomos appears, which means it cannot be divided. So, John Dalton, a British scientist put forward the hypothesis about atoms, among others:
- 1. The elements are composed of atoms which are small particles which cannot be subdivided
- 2. Atoms that make up the same element have the same properties, mass, and size, while for different elements, the properties are also different
- 3. Compounds are composed of two or more atoms in a fixed ratio
- 4. In chemical reactions, atoms after and before a reaction cannot be destroyed, only separation and reassembly occur
Point 3 shows the relationship with The Law of Constant Composition of Proust so that further research on atoms is more developed
Dalton's hypothesis is described as a solid sphere like a very small shot put ball or a bowling ball based on Dalton's hobby in bowling

INFORMATION:
We have the following statements
And we must complete them
STEP BY STEP EXPLANATION:
To complete the statements, we need to classify matter according to its state:
- Solid:
there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
- Liquid:
That describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
- Gas:
That describes the gas state, which we will consider in more detail elsewhere. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either.
Finally, we know that:
- A solid has a definite volume and has a definite shape
- A liquid has a definite volume and has not a definite shape
- A gas has not a definite volume and has not a definite shape
ANSWER:
- A solid has a definite volume and has a definite shape
- A liquid has a definite volume and has not a definite shape
- A gas has not a definite volume and has not a definite shape
