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.

Which of Dalton's statements about the atom was proven false by j.j Thompson?
One of Dalton's statements that was proven false by J.J. Thomson was the idea that atoms are indivisible and cannot be further divided. Thomson's discovery of the electron showed that atoms are made up of smaller particles, leading to the development of the plum pudding model of the atom.
What discovery lead j.j Thomson to decide that atoms were not indevisble but are actually composed of smaller parts?
J.J. Thomson discovered the electron through his experiments with cathode rays, which led him to propose the "plum pudding" model of the atom - where negatively charged electrons are embedded in a positively charged "pudding." This discovery challenged the idea that atoms were indivisible, suggesting they were composed of smaller parts.
What did Rutherford picture te atom as?
Rutherford pictured the atom as a miniature solar system, with a dense positively charged nucleus at the center and electrons orbiting around it in fixed paths. This model is known as the Rutherford model of the atom.
Scientist who coined the term atom?
The term atomos is Greek and means, roughly, "undivisable." It simply refers to anything that cannot be further split into any part. The modern concept of the Atom was introduced by Leucippus, further expounded by Democritus, and defined again by Lucretius. Lucretius is commonly given credit for the atom as we know it today. As for the discovery of the properties of the atom, John Dalton and his assistant found the weight of an atom.
Was Bohr the one who created the gold foil to find the positive nucleus of the atom?
No, it was Ernest Rutherford who conducted the famous gold foil experiment in 1909. This experiment led to the discovery of the atomic nucleus and the Rutherford model of the atom, which proposed that atoms have a small, dense, positively charged nucleus at the center. Niels Bohr later built upon these findings with his atomic model, which incorporated the idea of quantized electron orbits.
What discovery rejects the idea that atom is indestructible?
Its RADIOACTIVITY!! That was the first discovery that rejects the idea that the atom is indestructible
What discovery rejects the idea thatthe atom is indestructible?
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
Who proposed that all atoms cannot be divided or destroyed and that atoms of the same element are exactly the same?
Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.
Which description best matches Democritus and idea of the atom?
Democritus was an Ancient Greek philosopher who proposed the idea of the atom as the fundamental unit of matter, indivisible and indestructible. He believed that all matter is made up of these tiny, indivisible particles and that differences in properties arise from differences in the arrangement of these atoms.
What is the name of the philosophy that rejects the idea of universal?
Relativism or Relativity
What is the name of the philosophy that rejects the idea of universal values?
Moral relativism is the philosophy that rejects the idea of universal values, believing that moral principles are subject to cultural, historical, and individual differences.
Who first came up with the idea that the atom is mostly empty space?
The idea that the atom is mostly empty space was first proposed by Ernest Rutherford based on his gold foil experiment in 1909. This experiment led to the discovery that most of an atom's mass is concentrated in a nucleus at the center, surrounded by electrons in vast empty space.
Why did geologist rejects Alfred idea of continental drift?
He didn't have proof of a force causing the movement
What was Niels Bohrs major discovery?
Niels Bohr's major discovery was his model of the atom, known as the Bohr model. This model introduced the idea of quantized energy levels for electrons in an atom, explaining the stability of certain orbits and the emission of electromagnetic radiation. Bohr's work laid the foundation for modern quantum theory.
Does veto mean yes or no?
Veto does not mean to accept. Veto means one rejects the idea completely.
Who had the first idea about atom?
democritus
How can one effectively challenge or overcome an idea that seems indestructible, as the saying goes, "you can't kill an idea"?
One can effectively challenge or overcome an idea that seems indestructible by presenting strong evidence, logical arguments, and alternative perspectives. Engaging in open dialogue, critical thinking, and promoting education can help break down the barriers of entrenched beliefs. By encouraging empathy, understanding, and willingness to consider different viewpoints, individuals can work towards dismantling the perceived invincibility of an idea.
