What were John Dalton's hypotheses about atoms?

Answer 1

1. Atoms are impenetrable and aren't destructible. All material is made up of very, very small atoms.

2. All atoms of an element have the same mass and the same properties.

3. Mixtures are made by a fusion of 2+ unlike classifications of atoms.

4. A chemical reaction is a displacement of atoms.

Answer 2

John Dalton hypothesized that all matter is made up of indivisible particles called atoms, which differ in size, mass, and properties. He proposed that atoms of different elements have different weights and combine in simple whole number ratios to form compounds. Dalton also suggested that atoms are rearranged in chemical reactions but are not created or destroyed.

Answer 3

-Dalton told us that the basic unit of matter is the atom.

-compounds are formed when different atoms combine in fixed proportions

-all atoms of a given element are identical

-all element are composed of indivisible atoms
