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).

Who discovered Isotopes properties?
J.J. Thomson
Who invented isotopes?
Isotopes were not invented - they exist in nature. They were discovered when the atomic mass of Chlorine was measured at 35.5
Who discovered the mass of a proton and electron and the occurrence of isotopes?
Proton: Ernest RutherfordElectron and isotopes: J. J. Thomson
How will the modern periodic table be disturbed if isotopes of an element are discovered now?
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.

She discovered the elements radium and polonium.

Who is jj tompson?
He is the one who discovered electrons , isotopes and invented the mass spectrometer .
What kind of father in science jj Thomson?
He discovered electrons, isotopes, and invented the mass spectrometer.
What was Joseph J. Thomson's contribution to chemistry?
J. J. Thomson discovered the electron and the isotopes.
How did the discovery of isotopes lead J.J. Thomson to the description of the neutron?
The neutron was discovered by James Chadwick.
Are there no new elements to be discovered?
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may be discovered.
What is the decay element of uranium?
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
What did jj Thomas do?
I suspect you want J J Thomson. 1856-1940 Discovered the electron and isotopes, invented mass spectrometer.
