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 else can I help you with?
What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
Why was the discovery of radioactivity important?
The discovery of radioactivity was important because it led to the development of nuclear physics and important scientific breakthroughs, such as the understanding of atomic structure and the development of nuclear energy. It also paved the way for advancements in medicine, industry, and technology.
The weight in daltons of one atom of an element is?
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
What is a sentence for radioactivity?
Chernobyl is well-known for it's dangerously high radioactivity levels.
How many daltons does one molecule of water have?
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).

What was Sir Ernest Rutherford famous for?
Sir Ernest Rutherford was a pioneering physicist known for his contributions to the understanding of atomic structure and radioactivity. He is credited with developing the nuclear model of the atom and conducting the famous gold foil experiment, which led to the discovery of the atomic nucleus. Rutherford's work laid the foundation for modern nuclear physics.
How does Daltons atomic theory explain the law of definite proportions?

What part of daltons atomic theory was proved incorrect?
One part of Dalton's atomic theory that was proved incorrect is the assumption that atoms are indivisible and cannot be further subdivided. The discovery of subatomic particles such as protons, neutrons, and electrons showed that atoms are made up of smaller components.
Is it true that the atomic bomb couldn't exist without radioactivity?
Simply to put it Yes. Atomic Bombs is a form as Nuclear bomb and Nuclear products/elements such as Uranium 235 (a material used in a atomic bomb) emits radioactive particles. Radioactivity Particles = radioactivity.
The weight in daltons of one atom of an element is?
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
What is a sentence for radioactivity?
Chernobyl is well-known for it's dangerously high radioactivity levels.
Could the atomic bomb exist without radioactivity?
No, the atomic bomb relies on the process of nuclear fission, which produces radioactivity as a byproduct. Radioactivity is essential for the explosive power of the bomb.
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) .
If the atomic mass of oxygen is 16 and the atomic mass of hydrogen is 1 how do the current atomic masses compare to daltons?
Atoms are made up of protons, neutrons, and electrons. The atomic mass listed on the periodic table is an average of all the isotopes of an element, which includes the mass of the protons and neutrons. Therefore, the atomic masses listed for oxygen (16) and hydrogen (1) are in daltons.
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) .
