the emissions of small energetic particles from the core of certain unstable atoms. Most of the volume of the atom is empty space, throughout which tiny negatively charged electrons are dispersed. What are the main ideas in Dalton's atomic theory? Atoms combine in simple, whole number ratios to form compounds. read more

Dalton's Atomic Theory had several main points, which are variously grouped into five statements : 1) All matter is made of atoms. 2) Atoms of a given element are identical in size, mass and chemical properties. read more
The important point of Dalton's theory was that it created a logical basis for studying chemistry. Where before it was essentially a collection of disparate facts, with the atomic theory a start could be made on rationalising these facts and make chemistry a logical and quantitative science. read more
Chemical reactions involved the rearrangement of combinations of the atoms in a substance. Dalton's Atomic Theory had several main points, which are variously grouped into five statements : 1) All matter is made of atoms. 2) Atoms of a given element are identical in size, mass and chemical properties. read more
