Its itself
Dmocritus supposed that the smallest part of matter is an indestructible atom.
Atoms are indestructible by chemical methods; a principal characteristic of an atom is the number of protons.
Marie and Pierre Curie did not discover the atom. John Dalton is credited with the discovery of the atom and J.J. Thomson with the discovery of the electron.
Ofk
The discovery of the atom is attributed to the work of multiple scientists throughout history, such as John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. These scientists made significant contributions through their experiments and theories that led to our current understanding of the atom as the basic building block of matter.
Its RADIOACTIVITY!! That was the first discovery that rejects the idea that the atom is indestructible
The discovery of the fission reaction proved that the atom is not indestructible. Fission is a process by which an atom is split to to produce two atoms, smaller in size than the original atom. In addition the mass of the system after a standard fission reaction is less than the mass of the system before the reaction, some of the mass having been converted to energy. This indicated that it is possible to completely "destroy" an atom (although it is merely converted to a different form). Fission was first observed in 1938 by Otto Hahn who observed that after bombarding a uranium nucleus with neutrons, the much lighter barium was produced.
atom was described as tiny, hard, indestructible sphere by Newton.
Dmocritus supposed that the smallest part of matter is an indestructible atom.
no, because according to him an atom is a tiny indestructable sphere with mass on it.
This the atom; it is indestructible by chemical methods.
General relativity (Loosely speaking, e = mc^2) What's more, it's not just the theory that has proved that an atom can be destroyed; experimental data does too. The most famous example of this is the atomic bomb; atoms are converted into pure energy and...well you've probably seen pictures of what the explosion looked like. I hope this answers your question. PS: The atoms isn't technically lost, it's just converted into a form that has no mass
His MAJOR discovery was when he discovered the atom.
discovery of the atom's structure
The atom. Considered by Dalton to be indivisible and indestructible.
Atoms are indestructible by chemical methods; a principal characteristic of an atom is the number of protons.
the ancient Greeks made the atom, but they had no proof after the discovery.
