How does cathode ray differ from as anode rays?
Advertisements
Solution
| Cathode rays | Anode rays | |
| 1. | These rays travel from the cathode to the anode. | These rays travel from the anode to the cathode. |
| 2. | They are made of negatively charged particles. | They are made of positively charged particles. |
| 3. | They produce a greenish-yellow fluorescence on a soda-glass screen. | They produce fluorescence on a zinc sulphide screen. |
| 4. | They are affected by an electric field, i.e. they are inflected towards a positive field and deflected towards a negative field. | They are deflected by electric and magnetic fields but in a direction opposite to that of cathode rays. |

Define: Proton
Define: Neutron
Represent a proton ‘p’ in term of its symbol showing the subscript and superscript value.
Name or state the following.
Two elements having the same number of protons and electrons but a different number of neutrons.
Assertion: Proton can be defined as a hydrogen ion (H+).
Reason: These photons are produced when one electron is removed from one hydrogen atom.
