John Dalton's most important theory, developed in 1803, was that matter is composed of atoms of differing weights that combine in simple ratios.
Dalton published a book in 1808 listing the atomic weights of a number of known elements relative to the weight of hydrogen. Although not entirely accurate when published, those weights form the basis for the modern periodic table of the elements.
John Dalton has been honored by having his name used as the international Atomic Mass unit, equivalent to 1/12 of the mass of a neutral carbon-12 atom, the dalton.
The five main points of John Dalton's atomic theory are as followed: · 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. · Atoms of one element can combine with atoms of other elements to form 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.
by stating the five facts (now we know 2 of them aren't true) of an element.
Dalton described the relationship between atoms and elements using a tables, graphs, equations, and various pictures to create visuals with his explanations.

Was Dalton right in calling lime an element?
Lime is a compound of calcium and oxygen, so no, it is not an element.
John Dalton's atomic theory stated that atoms of the same?
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
John Dalton combined the idea of blank with the Greek theory of the atom?
John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.
Why is John Dalton's atomic theory still mentioned in science?
Scientists use Dalton's atomic theory even though parts of it have been proven wrong as the basis of other discoveries. His theory about atomic elements being the same was wrong but has been used for a long time even to the discovery of isotopes.
For what is John Dalton known for?
Chemical symbols and discovery and elaboration of atoms
Dalton used the lightest element as his standard for atomic masswhat is this element?
Hydrogen was used by Dalton as his standard for atomic mass.
Who were these scientists has an element named them Benjamin Franklin john Dalton Nikola Tesla Dmitri mendeleyev?
john dalton

According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
What did Dalton used the lightest element as his standard for atomic mass?
Dalton used hydrogen as his standard for atomic mass because it is the lightest element and was convenient for comparing the masses of other elements.
How the theorie of Dalton does contradict the theorie of isotopes?
In his time were not known the isotopes and Dalton supposed that all atoms of a chemical element are identical.
What year did Dalton say that Atoms of the same element exactly alike?
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.
Who came up with this quote all atoms of a given element are identical but they differ from those of any other element?
This quote is attributed to British physicist and chemist John Dalton, who proposed the atomic theory of matter in the early 19th century. Dalton's theory stated that all atoms of a given element are identical and have specific characteristics that differentiate them from atoms of other elements.
How do atoms define or determine elements?
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms
Define the term atom?
the smallest particle of an element that has chemical property of the element
When Dalton's theory is it possible to convert atoms of the one element into atoms of another?
No, according to Dalton's theory, atoms of one element cannot be converted into atoms of another. Atoms are indivisible and cannot be created or destroyed in a chemical reaction. This concept is known as the conservation of matter.
What is another name for the AMU of an element?
Atomic mass unit (amu) is also known as a Dalton (Da).
