2 shows the results of an experiment which led 1 to discover something. Identify 1 and tell us what he discovered using 2.

Really sorry for the late post people.

    1. J.J. Thomson
    2. Isotopes of Ne, the first evidence for isotopes of any stable element.

    Person in 1 is J.J. Thomson, physicist and nobel prize winner.
    His experiment in 2 , is first example of mass spectrometry , and from this experiment he discovered “isotopes” of a stable element (in this case neon)


  5. krudebox

    JJ Thomson who showed the existence of Isotopes and showed the technique of Mass spectrometry.


  6. 1. J J Thompson
    2. Discovery of neon isotopes


  7. J.J.Thompson.
    Parablous of neon.. lead to the discovery of two isotopes of Neon.. neon-20 and neon-22.. First example of mass spectrometry.

    JJ Thomson and the markings for the two isotopes of neon: neon-20 and neon-22 – his discovery of isotopes.

    The amazing Sir Joseph John Thomson.
    2 shows how otherwise stable elements can contain variations we call “Isotopes”.
    The plate is the earliest example of mass spectrometry.
    showing 2 different Neon isotopes in the parabolic curve paths they fall into on a photographic plate based on their mass after magnetic and electric fields are applied.


  11. nishansolo

    1 – J. J. Thomson
    2 – Thomson’s separation of neon isotopes by their mass, thus leading to the first isotopes of a stable element (Also an example of Mass Spectrometry).

    J.J. Thomson who passed different isotopes of Neon through an electric field and observed different deflections thus proving the existence of (stable) isotopes. This is also the first instance of the technique of mass spectroscopy.


  18. reddevil_ani

    J J Thompson discovered that stable elements have Isotopes.

    (2)Isotope discovered by (1)J.J Thomson


  21. Vardhan Shenoy

    1) J.J Thomson
    2) Isotopes. Using 2, he concluded that Neon is of 2 isotopes

    1 is jj thomson, and this experiment helped discover isotopes (of neon)


  29. 1. J.J. Thomson
    2. first evidence of isotopes of a stable element

    I quote
    “In 1913, as part of his exploration into the composition of canal rays, Thomson channelled a stream of ionized neon through a magnetic and an electric field and measured its deflection by placing a photographic plate in its path. Thomson observed two patches of light on the photographic plate (see image on right), which suggested two different parabolas of deflection. Thomson concluded that neon is composed of atoms of two different atomic masses (neon-20 and neon-22), that is to say of two isotopes. This was the first evidence for isotopes of a stable element; Frederick Soddy had previously proposed the existence of isotopes to explain the decay of certain radioactive elements.”
