Canal rays produced when hydrogen atoms are taken in the discharge tube constitutes

Options

A. Electrons
B. Protons
C. Neutrons
D. Nucleus

Answer

To solve the question "Canal rays produced when hydrogen atoms are taken in the discharge tube constitutes", we will follow these steps:

### Step 1: Understand the Concept of Canal Rays
Canal rays, also known as positive rays, are streams of positively charged particles that are produced in a discharge tube. They were discovered by the German scientist Eugen Goldstein in 1886.

**Hint:** Remember that canal rays are associated with positive charge and are distinct from cathode rays, which are negatively charged.

### Step 2: Identify the Source of Canal Rays
In a discharge tube, when hydrogen gas is used, and a high voltage is applied, the hydrogen atoms can lose electrons. This process results in the formation of positively charged hydrogen ions (H⁺), which are the constituents of canal rays.

**Hint:** Think about what happens to hydrogen atoms when they lose electrons in a discharge tube.

### Step 3: Analyze the Charged Particles
The positively charged particles that make up canal rays are primarily protons. Since hydrogen consists of one proton and one electron, when the electron is removed, the remaining particle is a proton.

**Hint:** Recall that the hydrogen atom is the simplest atom, consisting of one proton and one electron.

### Step 4: Evaluate the Options
Given the options:
- Electron
- Proton
- Neutron
- Nucleus

We can conclude that the canal rays produced from hydrogen atoms in the discharge tube consist of protons, as they are the positively charged particles that move towards the cathode.

**Hint:** Eliminate options based on their charge and the behavior of particles in the discharge tube.

### Step 5: Conclusion
The correct answer is that canal rays produced when hydrogen atoms are taken in the discharge tube constitute protons.

**Final Answer:** Canal rays consist of protons.
