Major credit for the discovery of noble gases is given to

Options

A. Cavendish
B. Ramsay
C. Rayleigh
D. None of these

Explanation

To solve the question regarding who is credited with the discovery of noble gases, we can follow these steps:

### Step 1: Understand the Context
Noble gases are a group of elements found in Group 18 of the periodic table. They are known for their lack of reactivity due to having a full valence shell of electrons.

**Hint:** Remember that noble gases include Helium, Neon, Argon, Krypton, Xenon, and Radon.

### Step 2: Identify the Key Figure
The question asks for the individual who is given major credit for the discovery of noble gases. It is important to look for a chemist who made significant contributions to the identification of these gases.

**Hint:** Look for a British physical chemist who is known for discovering multiple noble gases.

### Step 3: Review the Options
The options provided are:
- A) Cavendish
- B) Ramsey
- C) Relic
- D) None of these

**Hint:** Consider the historical contributions of each individual listed in the options.

### Step 4: Recall Historical Contributions
Sir William Ramsey is known for discovering several noble gases, including Neon, Argon, Krypton, and Xenon. He played a crucial role in establishing the existence of this group of elements.

**Hint:** Think about the significance of Ramsey's work and any awards he may have received for his discoveries.

### Step 5: Conclude the Answer
Based on the information gathered, the major credit for the discovery of noble gases is attributed to Sir William Ramsey, who was awarded the Nobel Prize in Chemistry in 1904 for his achievements.

**Final Answer:** The correct option is B) Ramsey.

### Summary of Steps:
1. Understand the context of noble gases.
2. Identify the key figure associated with their discovery.
3. Review the provided options.
4. Recall the historical contributions of the individuals.
