There were no technologies. The atom was discovered by the ancient Greek's. They figured that eventually if you kept on dividing something, it would get so small that you wouldn't be able to divide it anymore. There would be just one tiny particle left. They called this particle the atom. Of course over time the atom proved not to be the smallest particle with the discovery of the proton, electron and neutron.

What experiments did Thompson do?

J. J. Thomson observed that cathod rays are deflected by an electric field - and from this discovered the electron.


In the late 1800s experiments using cathode ray tubes led to the discovery of the electrons?

Yes, experiments with cathode ray tubes in the late 1800s, particularly by scientists like J.J. Thomson, led to the discovery of electrons. Thomson's experiments demonstrated that cathode rays were composed of negatively charged particles, which were later named electrons. This discovery laid the foundation for modern atomic theory.


What evidence did J.J Thomson provided about this structure of an atom?

J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.


What did JJ Thomson measure?

his important work was cathode ray experiment . he also discovere the natural radioactivity of pottassium.In his second experiment, he investigated whether or not the rays could be deflected by an electric field.in the third experiment he measured the mass to charge ratio of cathode rays by measuring how much they are deflected and how much energy they carries.


What is the photograph taken from using an electron microscope called?

The image taken from an electron microscope is called an electron micrograph or simply a micrograph. It provides a highly detailed and magnified view of the specimen being studied.

Who identified cathode rays as subatomic particles?

J.J. Thomson is credited with identifying cathode rays as streams of negatively charged subatomic particles, which were later named electrons. His experiments with cathode ray tubes led to the discovery of the electron and contributed to the development of the atomic theory.


Did JJ Thomson experiments that showed that atoms cannot be divided into smaller particles?

Yes, J.J. Thomson's experiments using cathode rays led to the discovery of the electron and the plum pudding model of the atom. This model suggested that atoms are not indivisible, but composed of smaller particles.

What was J J Thomson's biggest contribution?

Thomson discovered the electron in the year 1897.His work put forward a new theory, that atom was made up of small particles.Thus he discovered the electrons. He proved his theory using the cathode ray tube.

What is the purpose of using a streak plate in microbiology experiments?

The purpose of using a streak plate in microbiology experiments is to isolate and separate individual bacterial colonies for further study and identification.


What did jj thomas discover?

J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.
