What are the sub atomic particles for john daltons model?
protons,neutrons and electrons are the sub atomic particles
What discovery lead the scientists to question john daltons model of the atom and to favor jj Thomsons model?
JJ Thomson's discovery of electrons indicated that atoms were not indivisible.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
no.
What was one main point if daltons atomic theory?
ttha atoms made up pthe smallest forms of matter
How did the discovery of radioactivity contradict Dalton's atomic theory?
radioactivity proves that there are smaller particles in an atom that makes it up, they are proton, neutron, and electron. Dalton's atomic theory clearly states that the atom is the simplest particle. Radioactivity contradicts Dalton's theory since it proves that there are particles which are simpler than the atom.
What are the sub atomic particles for john daltons model?
protons,neutrons and electrons are the sub atomic particles
How does Daltons atomic theory explain the law of definite proportions?
asdfsdhd
What is the atomic mass of neon'?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .

What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
What main feature of daltons atomic model was abandoned after thomson's discoveries?
The idea that atoms are indivisible.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
no.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
What kind of information might be available to scientists today that would lead them to disagree with Dalton's atomic theory?
1. Discovery of isotopes: not all atoms of the same chemical element are identical. 2. Discovery of the atomic structure: atoms are indivisible by chemical methods but they are divisible with physical methods in components.
Does the existence of isotopes contradict part of Dalton's original of atomic theory?
Yes.
How did daltons atomic theory lead to the different model scientists have today?
Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
How did Dalton's atomic theory lead to the discovery of the atomic bomb?
it didn't
