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
What else can I help you with?
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.
What are the main three parts of an electrons used in the current atomic theory that describe an electrons location?
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.
Which parts of Daltons theory were later found to be erroneous?
Dalton's theory mistakenly proposed that atoms were indivisible and that all atoms of a given element were identical in size, mass, and other properties. However, we now know that atoms can be further subdivided into protons, neutrons, and electrons, and that isotopes exist with variations in mass.
What did John Dalton add to the atomic theory of Democritus?
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
What is the three parts of Dalton's atomic theory?
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.

What parts of daltons atomic theory is illustrated by 2 parts of hydrogen and oxygen forming water?
Dalton's atomic theory is illustrated by the combination of hydrogen and oxygen to form water in two ways: through the law of definite proportions, which states that compounds contain elements in specific ratios by mass, and through the law of multiple proportions, which states that different compounds can be formed by combining the same elements in different ratios.
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.
What parts of Dalton's atomic theory was changed?
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.
Where are each sub-atomic parts found?
Protons and neutrons are in the atomic nucleus; electrons are around nucleus.
Who wrote the first two parts of cell theory?
Theodor Schwann wrote the first two parts of the cell theory
What is the first atomic theory?
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.
Why is John Dalton's atomic theory still mentioned in science?
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.
What was Matthias Schleiden theory?
His theory was that all plant parts are made of cells.
Who wrote the first 2 parts of cell theory theory?
schleiden and schwann
What about job interviews is incorrect?
