Question

Anode rays particles are called?
A) Electron
B) Proton
C) Neutron
D) None of these

Answer 1

Hint: Anode rays incorporate positive charged particles. These rays are generated from the positive electrode.

Complete answer:
Cathode rays are discovered by Eugen Goldstein. When Eugen Goldstein applied electricity at high voltage through a gas at very depression taken in an exceedingly discharge tube, streams of heavy particles were expelled out by the anode (positive electrode). These streams of particles are called anode rays. Anode rays contain charged particles.

The mass and charge of the anode ray particles depends on the character of gas taken within the discharge tube. Different gases give differing kinds of anode rays which contain charged particles having different masses and different charges.

Goldstein explained the formation of protons as follows. Hydrogen gas consists of hydrogen atoms. When large electrical voltage is applied to hydrogen gas, the voltage ejects the electrons from the hydrogen atoms. After the removal of a charged electron from an atom, a charged particle called proton is made. These fast-paced protons from the anode rays. Hence the anode rays particles are called protons. These are positive charged particles.

Therefore the correct answer is option (B).

Note: It should be noted that hydrogen atoms are the lightest of all the atoms, so hydrogen atoms form the lightest positively charged particles called protons. The heavier atoms of other gases form heavier positively charged particles which are made up of a number of protons held together.
