How can you use Dalton's atomic theory to explain why every sample of pure substance has the same properties?

Dalton's atomic theory states that a pure substance is made up of tiny particles called 'atoms', and that each atom of a substance will be identical in shape, size and behavior to any other atom of that substance, regardless of source or location. Any two samples of a pure substance will demonstrate the same properties because all of these samples are comprised of identical atoms which behave identically.

Which item is a sign of chemical property of a substance?
A substance's Atomic Number is its most distinguishing property. It defines and describes It's chemical properties.
What is the atomic mass of neon'?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
Is a atomic change the same substance after it changes?
/the atomic structure defines the substance....changing the atomic configuration changes the substance to something else.....

Why do we need atoms?
According to modern Periodic Table Atomic numbers are the fundamentals in order to explain the properties of an atom.One thing more and that is the concept of isotopes also make the atomic masses less strong to explain atomic properties which has no effect on atomic numbers.
What are the sub atomic particles for john daltons model?
protons,neutrons and electrons are the sub atomic particles

Why do you need atomic numbers?
It tells you how many protons an atom of an element has. It is the basis of the arranegement of the periodic table and has taken the scientific world a long time to discover. About 1860 C. E. Mendeleyev published the first such table.

Are molecules the smallest units with the characteristic properties of a substance?
A molecule is the smallest unit with the characteristic properties of a molecular substance, i.e., one joined by covalent bonds. A single atom is the smallest unit with the characteristic properties of an elemental substance.
What main feature of daltons atomic model was abandoned after thomson's discoveries?
The idea that atoms are indivisible.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
no.
