istopes was discovered by joseph john and francis aston both discovered isotopes
-------------------
The first hypothesis on isotopes is from Frederick Soddy (1912); the practical confirmation is attributed to J. J. Thomson (1913).

Proton: Ernest RutherfordElectron and isotopes: J. J. Thomson
The periodic table would be disturbed only if isotopes of a new element are discovered, because a periodic table is based on order of atomic number, not atomic mass. If new isotopes of a previously known element were discovered, the atomic mass shown in the periodic table might be changed, but this is very unlikely because the atomic masses shown in a periodic table are based on the naturally occurring distribution of isotopes, and any newly discovered isotopes would probably occur only in very small fractions of the total.
Isotopes were not invented - they exist in nature. They were discovered when the atomic mass of Chlorine was measured at 35.5
No, J.J. Thomson did not discover isotopes. Isotopes were discovered by Frederick Soddy and John William Strutt in the early 20th century. J.J. Thomson is known for his discovery of the electron.

He is the one who discovered electrons , isotopes and invented the mass spectrometer .
The neutron was discovered by James Chadwick.
J. J. Thomson discovered the electron and the isotopes.
He discovered electrons, isotopes, and invented the mass spectrometer.
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may be discovered.

There are over 3,000 known isotopes in the world, with more being discovered as research progresses. Isotopes are variations of elements with the same number of protons but different numbers of neutrons. They play a crucial role in fields such as nuclear science, medicine, and environmental studies.
Frederick Soddy discovered isotopes through his collaboration with Ernest Rutherford in studying radioactivity. They observed that certain elements had multiple forms with different atomic weights but similar chemical properties, leading to the concept of isotopes. Soddy coined the term "isotope" in 1913 to describe these different forms of elements.
