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 discovery contradict components of Daltons atomic theory?
The discovery of subatomic particles, such as electrons, protons, and neutrons, contradicts Dalton's atomic theory, which stated that atoms were indivisible and uniform spheres. It was later revealed that atoms are not indivisible and are composed of smaller subatomic particles with varying properties.
Why was the Arrhenius theory of acids and bases modified?
The Arrhenius theory was modified because it was limited in its scope to only aqueous solutions and did not account for reactions in non-aqueous solvents. The Bronsted-Lowry theory extended the concept of acids and bases to include proton transfer reactions in all solvents, leading to a more inclusive and versatile understanding.
Who discovered the atomic theory?
john dalton developed the atomic theory , which he published in 1803
Which is not part of John Dalton atomic theory?
Atoms are made up of smaller particles.
Who did not have experimental evidence to support there theory of a atom?
Ancient Greek philosophers such as Democritus and Leucippus did not have experimental evidence to support their theory of the atom. Their idea of the atom was purely philosophical and lacked experimental verification until much later.
What idea proposed by Lamrack was later found incorrect?
Use and Disuse Theory
Which of Daltons statements about the atom was later proven false?
less than 100 years ago Dalton published his theory that atoms could not be broken down into smaller particles. Scientist have found out that they can in fact be broken down even further.
What is the scientific basis of the heliocentric theory?
Copernicus and later Galileo and Kepler. Venus was found to have phases Jupiter was found to have moons Elliptical orbits which Kepler found would later be described by gravity Start there.
Why was Alfred wegener's theory accepted ntil later?
YEs, Alfred WEGners theory was accpeted until later BECause This Question IS BEing ASked to aN ELEveN yEar OLdBecaysE sHE wANTs To Know :CAN A THEORY ALREADY ACCEPTED , BE REJECTED LATER WHEN A CONTRADICTION IS FOUND?THANKSI Appreciate if you would help.ByebyeX
How did Wegener's theory change after his death?
His theory stated that only continents move, we later found that plates are made of ocean pieces too, not just land masses.
What is a scientist hypothesis?
A hypothesis is a temporary explanation for some observation. It is then tested and, if is found to be incorrect, a new one has to be formed. If found to be correct, it becomes a theory. If that theory is later found to have a counter-example it is modified (hypothesis -> theory - same process) or a completely new hypothesis proposed and tested. The hypothesis alwasy comes before the theory. it is a practical explanation that the scientist develops that accounts for a theory.
Who first started the thoery of continetal drift?
Alfred Wegner, but people disbelieved him as he was not a proper geologist and he had no mechanism but evidence was later found which supported his theory.

Did ptolemy use the big bang theory?
No. The Big Bang theory came a lot later.
How would today be different if Nicholas Copernicus was never born?
we just wouldn't have figured out that our universe aws heliocentric until a little later Galileo agreed with Copernicus on his theory so we would have found it out still just a little later
When was the theory of relativity created?
The theory of relativity was introduced by Albert Einstein in 1905 with his special theory of relativity, and later expanded with the general theory of relativity in 1915.
What theories are supported by string theory?
The theory of extra dimensions, infinite universes, the theory where the Big Bang occurred when a membrane of a different dimension crashed into our membrane, gravitons, the theory that gravity seems weakest because gravitons, (open superstrings) can leak through other dimensions and universes. But the problem was that there were 6 theories, but later they found out that the 6 theories were 6 different point of view of the real theory of everything: M-Theory
