Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
How j.j Thomson discovered electrons are negative?
J.J. Thomson discovered electrons are negative by conducting experiments with cathode rays in vacuum tubes. He observed how the rays were attracted to a positively charged plate, leading him to conclude that the particles in the rays carried a negative charge, which he named electrons.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
The beam of alpha particles is deflected toward the negatively charged plate. This is because alpha particles are positively charged, and opposite charges attract each other.
What happens to a charged particle placed between two charged plates?
When a charged particle is placed between two charged plates, it will experience a force due to the electric field created by the plates. The particle will move in the direction of the force, either towards the positively charged plate or the negatively charged plate, depending on the charge of the particle and the plates.
What type of charge do alpha particles have?
The alpha particle is the nucleus of a helium atom and hence has 2 protons and 2 neutrons. The neutron is neutral and the proton has a +1 elementary charge. The alpha particle therefore has an elementary charge of +2
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.
Why are cathode rays deflected away from a negatively charged plate?
Cathode rays are deflected away from a negatively charged plate because they are negatively charged particles themselves. Like charges repel each other, so the negative cathode rays are pushed away from the negative plate.
Would be attracted to a negatively charged metallic plate of the basic atomic particles?
Positively charged particles, such as protons, would be attracted to a negatively charged metallic plate. Electrons, which are negatively charged, are repelled by the negative charge and would not be attracted to the plate.
Would an electron move toward the positive plate or negative plate?
First of all this isn't a question about Plate Tectonics . Plate tectonics is the behavior of the big geographical areas in which the world is divided in, known as plates. But, answering your question, an election is a negative charge and thus will be attracted to the positive plate.

What is the electrical charge on the plate that causes the beam to bend toward that plate?
The electrical charge on the plate that causes the beam to bend toward it is negative. This negative charge creates an electric field that interacts with the positively charged ions in the beam, causing them to be attracted towards the negatively charged plate.
Is alpha plate silver plate?
No, alpha plate is not silver plate. Alpha plate is a type of base metal plating that contains alpha brass, which typically consists of copper and zinc. Silver plate, on the other hand, is a thin layer of silver that is electroplated onto a base metal.
When placed between oppositely charged metal plates the region of a water molecule that is attracted to the negative plate is the .?
partially positively charged hydrogen end of the molecule.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes, cathode rays are deflected towards a positively charged plate in an electric field. The negatively charged particles in the cathode rays are attracted to the positive plate, causing the deflection.
How j.j Thomson discovered electrons are negative?
J.J. Thomson discovered electrons are negative by conducting experiments with cathode rays in vacuum tubes. He observed how the rays were attracted to a positively charged plate, leading him to conclude that the particles in the rays carried a negative charge, which he named electrons.
In thomson's experiment why was the glowing beam repelled by a negatively charged plate?
The experiment showed the relation of positive/negative charges. The beam was made of positively charged ions, which were repelled. -there is another answer to this question that says " because it was attracted to the positive charged plate" this is FALSE, this is just a person trying to make a smart remark. --------- Cathode rays are a beam of electrons; electrons are elementary particles with a negative electrical charge.
Why mass spectroscopy only measure positive ion?
It's because negatively charged ions would not be attracted to the negative plate so it's not accelerated and thus it would not reach the detector.
