John Dalton, the father of modern chemistry, said that atoms combine in simple whole-number rations to form compounds.
Dalton's atomic theory states that atoms of different elements combine in simple whole-number ratios when they form compounds.
John Dalton
1) elements are composed of atoms 2) atoms of same elements = 3) atoms of different elements not = 4) atoms fomr compounds in definite ratios H2O
no.
How can an STM help prove Daltons theory
The four points of Dalton's theory were: 1. All elements are composed of atoms. 2. All atoms of the same element have the same mass, and atom of different elements have different masses. 3. Compounds contain atoms of more than one element. 4. In a particular compound, atoms of different elements always combine in the same way.

In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
atoms are indivisible,tiniest particles of matter. they combine in simple whole no ratios to form elements or compounds. they can neither be created, nor destroyed.
1) Dalton never proposed any table 2) All elements in Mendeleev's table and in the modern periodic table are elements.
* All elements are made of tiny indivisible particles called atoms. * All atoms of a given element are alike but the atoms of one element differ from the atoms of every other element. * Atoms are not created, destroyed or converted into other kinds of atoms during chemical reactions. They are simply rearranged into new compounds. * Compounds result from the chemical combination of a specific ratio of atoms of different elements. (These are loose interpretations of his original five statements)
no.
One of the best ways to describe John Dalton's observations of elements is that they are made of small particles. The atoms join in simple whole number ratios when the elements react.
You think probable to isotopes: atoms of the same element but with different number of neutrons.
Atoms can combine to form compounds, in simple whole number ratios
The duration of When the Daltons Rode is -4860.0 seconds.
When the Daltons Rode was created on 1940-08-23.
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.
