Compounds have a fixed composition. What did dalton notice that all compounds have in common? Cathode rays are negatively charged, these particles have a small mass, All elements have these particles, atoms are made of subatomic particles.
He noticed that matter always combined in fixed ratios based on weight, or volume in the case of gases. Chemical compounds always contain the same proportion of elements by mass, regardless of amount, which provided further support for Proust's law of definite proportions
law of definite proportions
The law of definite proportions states that a given chemical compound always contains the same elements in the exact same proportions by mass.
What did John Dalton suggest about what compounds were made of?
How does Dalton's atomic theory differentiate between elements and compounds? This theory states that elements combine in fixed, whole-number ratios to form compounds. Therefore, it suggests that compounds are made up of molecules that contain two or more atoms of different elements.
What conclusions did Dalton make about compounds?
Dalton's Experiments He researched the properties of compounds, which are substances that consist of more than one element. He showed that a given compound is always comprised of the same elements in the same whole-number ratio and that different compounds consist of different elements or ratios.
What were Daltons major findings?
John Dalton is best known for what became known as Dalton's law, which posits that the total pressure of a gaseous mixture is equal to the sum of the partial pressures of the individual component gases, partial pressure being the pressure that each gas would exert alone within the volume of the mixture at the same ...
What 4 Things did Dalton say about the atom?
1) All matter is made of atoms. Atoms are indivisible and indestructible. 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
Why is Dalton's Atomic Theory important in explaining the characteristics of compounds?
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.
How did Dalton explain the formation of compounds?
All matter consists of indivisible particles called atoms. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.
What are the 5 main points of Dalton's atomic theory?
His theory contained five main propositions:All matter is comprised of tiny, definite particles called atoms.Atoms are indivisible and indestructible.All atoms of a particular element share identical properties, including weight.Atoms of different elements contain different mass.More items...
What are the 5 most important points in Dalton's atomic theory?
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 can combine in simple whole number ratios to form chemical compounds.

What do all compounds have in common? Two things are true of all compounds: A compound always has the same elements in the same proportions. For example, carbon dioxide always has two atoms of oxygen for each atom of carbon, and water always has two atoms of hydrogen for each atom of oxygen. A compound always has the same composition throughout.
