Question

What are the five major points of in their atomic theory?

Answer 1

answer is :Dalton's theory was based on the premise that the atoms of different elements could be distinguished by differences in their weights. He stated his theory in a lecture to the Royal Institution in 1803. The theory proposed a number of basic ideas:

Elements are made of extremely small particles called atoms.Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.Atoms cannot be subdivided, created, or destroyed.Atoms of different elements combine in simple whole-number ratios to form chemical compounds.In chemical reactions, atoms are combined, separated, or rearranged.

Answer 2

1) elements are made of extremely small particles called atoms.
2) these elements will be identical in size, mass and other properties.
3) atoms cannot be destroyed or created.
4) atoms of different elements combine in simple whole number ratios to form chemical compound.
5)in a chemical reaction atoms combine, separate or rearrange.

Hope my answer helps you.
