The first atomic model was THE
solid sphere model
Who came up with the concept of the Solid Sphere Model and more importantly, what is it?
The Solid Sphere Model was the first atomic model and was developed by John Dalton in the early 19th century. He hypothesized that an atom is a solid sphere that could not be divided into smaller particles. He came up with his theory as a result of his research into gases. He realized that certain gases only combined in specific proportions.
So then what happened?
With an assortment of experiments and reasoning he was able to hypothesize that elements combine at the atomic level in fixed ratios. So, then he came up with some laws. These were:
What's the significance of John Dalton's discovery?
His discoveries as well as atomic theory made modern chemistry and physics possible.
Are these laws still held to be true?
Well as a matter of fact, some of the laws have been invalidated.

So then what happened?
With an assortment of experiments and reasoning he was able to hypothesize that elements combine at the atomic level in fixed ratios. So, then he came up with some laws. These were:
- Pure elements consist of small indivisible spheres called atoms.
- All of the atoms of an element are identical.
- Atoms of different elements can be told apart by their atomic weights.
- Atoms of elements unite to form chemical compounds.
- Atoms can neither be created or destroyed in a chemical reaction.
