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?
No, postulate 4 of Dalton's atomic theory, which stated that atoms of the same element are identical, is not entirely true. We now know that isotopes exist, which are atoms of the same element with different numbers of neutrons. This means that atoms of the same element can have slightly different masses.
What are five points of Daltons atomic theory and witch where proven wrong?
Dalton's atomic theory includes the following five points: 1) All matter is composed of indivisible atoms; 2) Atoms of the same element are identical in mass and properties; 3) Compounds are formed by the combination of different kinds of atoms; 4) A chemical reaction involves the rearrangement of atoms; 5) Atoms cannot be created or destroyed in a chemical reaction. However, points one and two were proven wrong; atoms are not indivisible (they can be split into subatomic particles) and isotopes show that atoms of the same element can have different masses.
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
The 2 protons in the helium atom have a totalof how many daltons?
The 2 protons in a helium atom would have a total of approximately 4 daltons. Each proton has a mass of approximately 1 dalton.

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
What did Aristotle's atomic theory state?
Aristotles theory stated that all substances were built from 4 elements, earth, air, fire, and water

Who discovered the atomic theory?
john dalton developed the atomic theory , which he published in 1803
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 are the three main points to John Daltons atomic theory?
All matter is made up of tiny, indivisible particles called atoms. Atoms of the same element are identical in size, mass, and properties, while atoms of different elements differ in these aspects. Chemical reactions involve the rearrangement of atoms, but atoms are neither created nor destroyed in chemical reactions.
The 2 protons in the helium atom have a totalof how many daltons?
The 2 protons in a helium atom would have a total of approximately 4 daltons. Each proton has a mass of approximately 1 dalton.
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.
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, Dalton's atomic theory is still relevant today. While some parts of his theory have been modified or expanded upon based on new scientific discoveries, the main principles of atoms being the building blocks of matter and elements being composed of individual atoms remain key concepts in modern atomic theory.
