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.

What did John Dalton do in 1803?
In chemistry, Dalton came up with the atomic theory upon which modern chemistry is based on today. This is because the Dalton theory allows for much simpler formulas, which was a major advantage for chemists everywhere.Dalton was an early chemist who believed that the atom was a solid sphere that could not be destroyed or cut into smaller portions.His atomic theory has five main points:all matter is made of atoms, which are indivisible and indestructible.all atoms of a given element are identical in mass/properties.atoms of a given element are different from those of any other type of element. as a result, atoms of different elements can be set apart from one another by their respective relative atomic weights.compounds are formed through combinations of 2 or more kinds of atoms and a given compound always has the same relative numbers of each type of atom.rearrangements of the atoms are called chemical reactions.He came up with his atomic theory by using Joseph Louis Prout's law of definite proportions as a basis and then added his own law of multiple proportions.
Statements are inconsistent with Dalton's atomic theory?
1)One problem with his atomic theory was that it claimed that all matter is composed of tiny indivisible atoms. We now know that atoms are divisible and are composed of smaller, subatomic particles (electrons, protons, and neutrons). 2)He also stated that atoms of an element are identical in mass- this is incorrect because all elements have isotopes (atoms with this same proton number but different numbers of neutrons) which means that atoms of an element do not have to have the same mass.
What was Seaborg's last major change to the Periodic Table?
seaborgium, the chemical element of atomic number 106, a very unstable element made by high-energy atomic collisions.
What is the major difference the bohr model and the currently accepted atomic model?
Bohr assumed that electrons moved in fixed orbits.
What did democritus discovered?
He didn't "discover" anything. He took a wild guess about what very small pieces of matter were like based on really no tangible evidence whatsoever and happened to be approximately correct if you're not too terribly picky about the details.

Dalton's atomic theory was a major contribution to discover the atomic structure in despite of been completely counterproved.
The two ancient greek theories of matter were the what theories?
Ancient Greeks had two major theories of matter. These were the Atomic theory of matter and the theory of pangenesis.
What was john Dalton's major constraint when he suggested his Atomic Theory?
Dalton's theory is very simple, yet his atomic model satisfactorily explained many familiar phenomena and the laws of chemical change. His theory prevailed for almost a century. Later, however, this model was modified as more sensitive and sophisticated equipment were develop and with new pieces of evidence were gathered wWhat do you think was john Dalton's major constraint when he suggested his atomic model?

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.

What was max planck major contribution to the atomic theory?
I don't know of atomic theory, but he came up with the idea that light energy acted like packetts of energy that he called photons. Thru some theoretical calculations he came up with Plank's constant that deals with the energy of different wavelengths of light.
What major contribution did john Dalton made to the atomic theory?
Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
