Well, I found information under Marie Curie and her husband Pierre Curie. Marie Curie found radium and in that - radioactivity. Radioactivity are really rays or tiny particles emitted by atoms. They discovered if atoms were in fact emitting such rays, it cannot be indivisible. Atoms are actually made up of smaller particles that can be rearranged. I'd check under this lead. Hope this helps!
------------
The atom contain protons, neutrons and electrons.
Neutrons and protons contain different types of quarks and gluons.
What else can I help you with?
Which part of Dalton's theory did Thomson's findings dispute?
The atom is the smallest known particle.
What is the smallest indivisible particle of an element?
The smallest indivisible particle of an element is an atom. Each atom consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.
What jj Thomson discover?
J.J. Thomson discovered the electron, a subatomic particle found in all atoms. This discovery led to his development of the plum pudding model of the atom, which revolutionized our understanding of atomic structure.
What did chadwhicks experiment kead to the discovery of?
Chadwick's experiment led to the discovery of the neutron, which is a subatomic particle with no charge located in the nucleus of an atom. This discovery helped to further our understanding of atomic structure and the composition of matter.
Can a particle be a single atom?
Yes, a particle can be a single atom.
What is the discovery of which particle proved that the atom is not indivisible?
protons
Which part of Dalton's theory did Thomson's findings dispute?
The atom is the smallest known particle.
What is the smallest indivisible particle of an element?
The smallest indivisible particle of an element is an atom. Each atom consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.
What is an atom and an example of an atom?
is the smallest indivisible particle which can exists on its own eg. an atom of fluorine.
What is the smallest indivisible particle of a substance called?
Either an atom or a molecule, depending on the substance.
Why is an atom not really indivisible?
An atom was once thought to be indivisible, but modern science has shown that atoms are made up of even smaller particles called protons, neutrons, and electrons. The discovery of subatomic particles through experiments such as particle accelerators has disproven the idea of atoms being indivisible.
The fundamental particle of a chemical element according to Daltons theory is?
The atom. Considered by Dalton to be indivisible and indestructible.
How did J J Thomson discovery change Dalton's theory?
J.J. Thomson's discovery of the electron showed that atoms were not indivisible as Dalton thought, but were made up of smaller subatomic particles. This led to the development of the plum pudding model of the atom, which replaced Dalton's solid indivisible atom theory.
What jj Thomson discover?
J.J. Thomson discovered the electron, a subatomic particle found in all atoms. This discovery led to his development of the plum pudding model of the atom, which revolutionized our understanding of atomic structure.
What did the Greeks named what they believed to be the tiniest particle of matter a?
The Greeks named the tiniest particle of matter "atom," stemming from the Greek word "atomos" meaning indivisible. They believed atoms were the building blocks of all matter and could not be further divided.
What is greek for indivisible in science?
Atom
Were democritus's views of the atom based on experimental evidence?
No, he theorized that there was a small indivisible particle (he called the "atom" because it means indivisible), but he never did any experiments to prove his theory. Around the same time, Aristotle believed that matter could be divided infinitely. Both were considered speculation until the eighteenth century.
