Three laws during Dalton's time were the law of definite proportions, law of multiple proportions and law of conservation of mass. According to law of conservation of mass, there is no loss of mass during any chemical reaction. Dalton's proposition that atoms are not destroyed or invented. The atoms merely realign themselves in a chemical reaction; so there is no loss of mass. According to the law of multiple proportions, when 2 elements form more than 1 compound, the different masses of one element that combine with the other element are connected to each other in small whole ratios. For example, in the case of nitrogen dioxide and nitrogen monoxide. One atom of nitrogen combines with one atom of oxygen for nitrogen monoxide. One atom of nitrogen combines with two atoms of oxygen for nitrogen dioxide. In the case of law of definite proportions, it is stated that a chemical compound always has precisely the same proportion of elements in terms of mass. According to Dalton's atomic theory, matter consists of atoms and one type of atom is allocated for each element. Compounds were actually combinations of various kinds of atoms in fixed ratios.

What technology did Dalton use for his atomic theory?
Dalton's atomic theory was based on the use of experimentation and observations from chemical reactions. He did not use any specific technology, but relied on the principles of matter conservation and chemical combination to propose the idea of atoms as the building blocks of matter.
What are Dalton points in the atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
What evidence led Dalton to propose his atomic theory?
Dalton's atomic theory was based on his observations of chemical reactions and the Law of Multiple Proportions, which showed that elements combined in simple ratios. He also analyzed the behavior of gases and proposed that they were composed of individual particles. Additionally, Dalton's work on the behavior of gases led him to propose that atoms of different elements had different weights.
Who was considered the father of atomic theory?
John Dalton is considered the father of atomic theory. He proposed that all matter is made up of indivisible particles called atoms, which combine in specific ratios to form compounds. Dalton's theory laid the foundation for modern chemistry and our understanding of the atomic structure.
What was Dalton's atomic model nickname?
Dalton's atomic model was often referred to as the "Billiard Ball Model" because he envisioned atoms as solid, indivisible spheres similar to billiard balls.

According to Dalton's atomic theory what can atoms do in a chemical reaction?
separate from atoms they are attahed to, and combine with other atoms
What benefit did chemists derive from Dalton's atomic theory?
Chemists benefited from Dalton's atomic theory by gaining a better understanding of the composition and behavior of matter at the atomic level. This theory provided a foundation for modern chemistry and helped explain various chemical reactions and properties of elements.
How does Dalton atomic theory explain the law of conservation of mass?
Dalton doesn't explain the law of conservation of mass.
Is atomic nuclei required in a chemical reaction?
No, atomic nuclei is not required for a chemical reaction.
According to Dalton what happens to atoms during a chemical reaction?
Combine with other atoms Separate from other atoms they are already attached to.
Why was Dalton atomic weight table inaccurate?
-He didn't know the correct ratio of atoms in a chemical reaction and the equipment at the time did not have very accurate numbers.
What is the first theory to relate chemical changes to events at the atomic level?
The first theory to relate chemical changes to events at the atomic level was proposed by John Dalton in the early 19th century. Known as Dalton's atomic theory, it stated that elements are composed of indivisible particles called atoms, and chemical reactions involve the rearrangement of these atoms to form new substances.
What postulate of Dalton's atomic theory is based on the law of conservation of mass?
Through his experiments, John Dalton was able to show that, even through chemical reactions, the beginning mass of the reactants and the final mass of the products were equal.
What scientist said matter is made of atoms?
The scientist who first proposed that matter is made of atoms was John Dalton, in the early 19th century. Dalton developed atomic theory to explain chemical reactions and the behavior of gases.
