Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?
ernest Rutherford
How did thomas discover the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
How did JJ Thompson demonstrate the existence of the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
Who performed the cathode ray experiment which led to the discovery of the electron?
Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. Thompson also believed that electrons float in a "pudding" of positive charges.
A cathode ray is deflected away from a negatively charged object What property of the cathode ray is shown by these phenomena?
The property shown by the phenomena is that the cathode ray is negatively charged. A cathode ray is also called an electron beam or an a-beam.
Why are cathode rays deflected away from a negatively charged plate?
Alpha Rays are attracted to a negatively charged plate because they consist of positively charged particles.
Who discovered the nucleus using his gold foil?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.

How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
A cathode ray produced in a gas-filled tube is deflected by a magnetic field A wire carrying an electric current can be pulled by a magnetic field A cathode ray is deflected away from a negatively?
They are negatively charged
Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.

When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.

How was it shown that atomic nuclei are positively charged?
when Rutherford did his experiment he got a observation that very few alpha particles (helium ions ) got deflected from their mean position . This indicates that there is very tiny positively charged particle or object is present . This led to the result that Nucleus is positively charged .
