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.

Did postulate 4 of Daltons atomic theory holds true now?
This postulate is valid today only in some situations.
Which of daltons 4 ideas were proven incorrect?
That atoms were indivisible.
How did Isaac Newton contribute to the atomic theory?
Im sorry 4 not being completely sure, but................. Newton believed in atomic forces. He thought that atoms and atomic power could not be properly understood without the use of quantum mechanics. -Sorry TJ
What is the difference of John Dalton's atomic theory to today's atomic theory?
Although Dalton's theory remains valid in modern atomic theory, there are some differences. Dalton's theory stated that atoms were indivisible and indestructible, but discoveries in modern atomic theory showed that there are subatomic particles that are smaller than the atom. Similarly, through nuclear reactions, an element's atoms can be transformed into atoms of another. Modern atomic theory includes isotopes while Dalton's theory does not have this phenomenon.
4 sub-atomic paricle composition of 4 atoms?
By definition you can't have a sub-atomic particle composed of 4 atoms. Sub-atomic means less than atomic. Unless I've misunderstood your question.
Did postulate 4 of Daltons atomic theory holds true now?
This postulate is valid today only in some situations.
What are the three main points to John Daltons atomic theory?
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
What are the 5 main atomic theories?
1) matter consist of small indivisible particles called atoms 2) atoms - neither created nor destroyed 3) they are alike in all aspects & differ from all other element. 4) atoms combine with other atoms in simple whole number ratios forming molecules 5) an atom is the smallest unit of matter these are the 5 points of DALTONS ATOMIC THEORY
Who discovered the atomic theory?
john dalton developed the atomic theory , which he published in 1803
Which of daltons 4 ideas were proven incorrect?
That atoms were indivisible.
What did Aristotle's atomic theory state?
Aristotles theory stated that all substances were built from 4 elements, earth, air, fire, and water
What was Daltons idea?
Dalton's atomic theory suggested that:different elements have atoms of different weights, and that all atoms of a given element are identicalatoms form compounds in the same relative quantities, and their relative ratios are always integersatoms are indestructible
What major contributions did Aristotle make to the atomic theory?
Aristotle did not believe in the Atomic Theory. He believed that everything was made up of only 4 elements fire, water, air, and earth. This theory was proven incorrect as is evidenced by the periodic table of elements. In short the answer to this question is, none.
How did Isaac Newton contribute to the atomic theory?

if a lithium nucleus contains 3 protons and 4 neutrons. What is its atomic mass?
Lithium by default contains 3 protons and 4 neutrons so its atomic mass is 6.941 amu (atomic mass units)
Does Dalton's 4 of atomic theory exists today?
yes, but only recently have scientist started to accept the atomic theory with sustainable evidence
Is postulate no 4 of Dalton atomic theory right in modern chemistry?
No, because today are known an immense number of nonstoichiometric compounds (also called berthollides).
