How where atoms discovered to be made of electrons?
1. Atoms are made from the atomic nucleus (protons plus neutrons) and electrons.2. For the discovery of electrons is credited J. J. Thomson in 1897.
Who is the father of atom?
Atoms played a role in Greek philosophy, but ancient idea of atoms had a different foundation than the modern one. The modern idea of atoms was presented in a paper by British scientist John Dalton in 1803. Mendeleyev created the periodic table in 1869. J.J. Thomson discovered the electron in 1897.
What ideas about atoms changed when new evidence was discovered?

Describe the discovery that demonstrate for the first time that atoms are not the smallest particles of matter?
The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.
What did thompson contribute in forming the modern model of the atom?
JJ Thomson discovered that atoms were not indivisible because he discovered that atoms contained negatively charged subatomic particles which he called electrons.

What were JJ Thomson's discovery?
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
Who made the earliest discovery of atoms?
Democritus, a Greek scholar, actually proposed the theory of tiny particles called atoms, but they weren't actually discovered by him but by a man by the name of John Dalton in the late 1700s.
Whose discovery of radium changed the worlds view of the atoms?
Radium was discovered by the Curies in France in 1898, in samples of pitchblende which were found to be radioactive after removal of the uranium.
Did martin klaproth discovered nuclear energy?
Martin Klaproth did not discover nuclear energy, he discovered the atoms uranium, zirconium, and cerium. The discovery of nuclear energy is credited to several people, including Albert Einstein and Marie Curie.
What was the result of the discovered how atoms combine into molecules?
What was the result of the discovered how atoms combine into molecules
When did the discovery of the democritus come about?
Particular what discovery? Democritus discovered atoms it was 400 BC. He believed that all matters are composed of atoms. he also believed that one can could take a specimen of matter and keep on subdividing it until it could no longer be further subdivided. The smallest piece of indivisible matter was called atom. For Democritus, atoms of water were smooth and atoms of fire have sharp edges. by JOVENLO NEGRIDO. PHYSICAL SCIENCE (EAC CAVITE)
Who discovered the different parts of the atom?
