![]() This means that any given element has atoms that must be identical in properties, including their mass. All atoms can be identified by mass and properties.This means that everything that is made of matter is composed of atoms, which are indivisible by design. This means that there are five components to the atomic theory that are offered by Dalton. When Dalton proposed his atomic theory, it was based on ideas, assumptions, and principles more than facts that were directly observable. ![]() The Four Principles of Dalton’s Atomic Theory Now other items could be added to the salt to change it, but the core atoms of salt are always the same. That means if you were to look at salt crystals, then you would have the same proportions of the base elements, chlorine and salt, no matter how much salt you had or where you got the salt. The law of constant composition says that pure compounds will always have the same proportion of the same elements. It is for this reason that mathematics seeks to create equality and balance. This means if a chemical reaction happens to create something new, then the amount of each element must come from the same starting materials. The law of conservation of mass says that within a closed system, no matter can be created or destroyed. His theory was based on two verified scientific laws: the law of conservation of mass and the law of constant composition. John Dalton’s atomic theory experiment was the first attempt to describe all matter by way of atoms and their properties in a way that was complete. ![]()
