Which of the following most accurately represents John Dalton’s model of the atom? A. a tiny, solid sphere with an unpredictable
valkas [14]

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
