Dalton thought that all atoms of an element are identical but we now know that there are different isotopes within an element (as long as the number of proton remains the same) and also he believe atoms were the smallest particles and therefore individual but we now know there are subatomic particles within an atom. I hope that helps, I just had to answer the same question for chemistry homework
The false part about Dalton's theory is the fact that he thought that an atom was completely made up of electrons. But really its basic essential parts were a nucleus, protons, neutrons, electrons, proteins...: p no not proteins just kidding but you get the point. I think this is the answer I did this off the top of my head and when I find out more I'll give you the correct answer. I mean come on I'm only 14

THANKS FOR READING,

Two of Dalton's principles of atomic theory are erroneous. According to Dalton, all atoms in an element are uniform which is false. Another principle is that atoms are indivisible, which is clearly wrong since atoms contain subatomic particles.
The indivisibility of an atom was proved wrong, for, an atom can be further subdivided into protons, neutrons and electrons.
dalton was wrong about atoms being indivisible. atoms are divisible into several subatomic particles. dalton was wrong about all atoms of a given element having identical properties.
An electron configuration shows the distribution of electrons among the subshells. Each number shows the principal quantum number, or shell, the subshell and finally the orbital of the electron.
There are three parts to Dalton's Theory of Atoms. All things are made up of atoms Atoms are indivisible and unbreakable/indestructible Compounds are formed by a combination of two or more atoms that are different
- Atomic number - Symbol - Name of element - Atomic mass they are not in order.. Hope i helped :-P
There are five parts to The Atomic Theory: 1.All matter is composed of extremely small particles called atoms. 2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.' 3.Atoms cannot be subdivided, created or destroyed. 4.Atoms of different elements combine in simple whole-number ratios to form chemical compounds. 5.In chemical reactions atoms are combined separated or rearranged.

Atoms can combine to form compounds, in simple whole number ratios
dalton was wrong about atoms being indivisible. atoms are divisible into several subatomic particles. dalton was wrong about all atoms of a given element having identical properties.
he made a mistake in assuming that the simplest compound of two elements must be binary, formed from atoms of each element in a 1:1 ratio, and his system of atomic weights was not very accurate - he gave oxygen an atomic number of seven instead of eight. Despite these errors, Dalton's theory provided a logical explanation of concepts, and led the way into new fields of experimentation.
Protons and neutrons are in the atomic nucleus; electrons are around nucleus.
john Dalton who lived between 1766-1844 was the first to use it "atomic theory of matter"around 1803 John Dalton put it together. Dalton was a teacher and a scientist(british you know) a few years later Dalton wrote a book called "a new system of chemical philosophy" i am unfamiliar with the actual contents of the book, but i do know that he is the first/origin to identify elements using symbols. also the name sake Dalton is a standard for atomic weights and units.. example the atomic weight is 2200 daltons. speaking of elements. if you ever come across element 115 its worth 600 + per pound. i do hope i helped you " a little "genaactually, Democratis was the first to use it, Dalton did discover another big thing in atomic history[look above] but Democratis, an ancient greek was the first to discover and use it. A famous quote by him is "convention bitter, convention sweet, in reality, atoms and void."Basically matter is made up of atoms, which are composed of varying numbers of positively charged protons and neutrally charged neutrons in a nucleus, orbited by negatively charged electrons. Atoms are the basic substance of elements, thus the table of elements which arrange them. Atoms join to form molecules and molecules join to form compounds.Atomic theory refers to the theory that states that all the matter is made of very small indivisible atoms.
Theodor Schwann wrote the first two parts of the cell theory
There were many scientists that worked on trying to prove that atoms exist. Neils Bohr was one of the first to discover that atoms had three parts and the electrons orbited the nucleus in 1913.
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.
His theory was that all plant parts are made of cells.
