of course Dalton's atomic theory is still believed today. but it has some defects, like his first postulate states that an atom is indivisible. but as you know its not correct. but the 4th and 5th postulate of his were exactly correct and are still the basis today. for a better answer please check on wikipedia.

How is the modern atomic theory different from Daltons atomic theory?
In Dalton's theory the electrons in the atom travel in a one layered orbital rotation around the nucleus, in the modern, or electron cloud, theory the electrons travel in a more radical patterned movement while still staying in their respected energy levels.
If all four postulates of Daltons atomic theory are correct what would change about the boxes on the periodic table and Why?
If all four postulates of Dalton's atomic theory were correct, the boxes on the periodic table would not change. Dalton's theory helped establish the concept of elements as composed of atoms, leading to the organization of elements on the periodic table based on their atomic number and properties. The periodic table would still be structured according to the number of protons in the nucleus of each element's atom.
What did the scientist who developed the modern theory of atomic structure base his theories off of?
Discovery of electron, proton and the neutron are fundamental for the theory of atomic structure.For this structure physicisits work from about 140 years and the research still continue.
How many what postulates of Dalton's atomic theory are still scientifically accepted?
Two postulates of Dalton's atomic theory are still scientifically accepted: the first being that elements are made up of tiny particles called atoms, and the second being that all atoms of a given element are identical in mass and properties.
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.
Is Dalton's model still useful?
Yes, Dalton's atomic model is still a useful conceptual framework for understanding the basic structure of matter. However, it has been revised and expanded upon with modern advancements in atomic theory such as the discovery of subatomic particles.
What portion of daltons atomic theory is still considered correct?
Dalton believed that all elements were composed of tiny indivisible particles called atoms. We now know that this is not true, there are particles found within the atom: protons, neutrons, & electrons. Dalton believed that all atoms of the same element were identical. We know this is not true. Isotopes are atoms of the same elemtn that have different mass numbers because of different numbers of neutrons, therefore, all atoms of the same element are NOT identical
Is Judaism still believed by some?
Yes, believed and practised ... still.
Which of Dalton's ideas about atomic theory have been applied to current atomic theory?
all matter is made up of units called atoms atoms can bond to and un-bond from each other all atoms of the same element are identical. atoms can form bonds during chemical reactions the basic unit of matter is an atom atoms will have identical atomic mass if they are the same element
When was the atomic theory discovered?
Leucippus is a mysterious figure whose exact dates are unknown - some say he never existed - but is still considered the be the founder of the Atomistic theory. Democritus was born 460 B.C. and died 370 B.C. He was a disciple of Leucippus and both men are credited with the atomistic theory.
Did the existence of isotopes affect the validity of the atomic theory?
Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size." We know that this cannot be true because isotopes of the same element, oxygen for example O-16 and O-17, have different mass numbers (atomic mass). Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size."

Scientific alternatives to Darwin's theory of evolution?
Darwin's original theory was formulated over 150 years ago. The modern theory of evolution, while still basically the same as Darwin's, is also significantly different. In either case, there is no scientific alternative to the origin of biodiversity.This is equivalent to how there is no scientific alternative to Atomic Theory.
