Which of the following gradation in the properties is false, as we move from Left to right in the periodic table ?

Options

A. Metallic to non-metallic character
B. Oxidising to reducing properties
C. Metallic solids through network solids to molecular solids
D. Base forming to acid forming character

Answer

To determine which gradation in properties is false as we move from left to right in the periodic table, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Trend in the Periodic Table**:
- As we move from left to right in a period of the periodic table, certain properties of elements exhibit predictable trends. These trends include changes in metallic character, non-metallic character, oxidizing and reducing properties, and acid-base character.

2. **Analyzing Each Option**:
- **Option 1: Metallic to Non-metallic Character**:
- As we move from left to right, metallic character decreases while non-metallic character increases. This statement is **true**.

- **Option 2: Oxidizing to Reducing Properties**:
- When moving from left to right, the tendency to gain electrons (oxidizing property) increases, while the tendency to lose electrons (reducing property) decreases. Therefore, this statement is **false** because it incorrectly suggests that oxidizing properties decrease from left to right.

- **Option 3: Metallic Solids through Network Solids to Molecular Solids**:
- This statement is true as we transition from metals (which are typically metallic solids) to non-metals (which can form network solids and molecular solids).

- **Option 4: Basic to Acidic Forming Character**:
- As we move from left to right, metal oxides (which are basic) transition to non-metal oxides (which are acidic). Thus, this statement is also **true**.

3. **Conclusion**:
- The only false statement among the options provided is **Option 2**: "Oxidizing to reducing properties."

### Final Answer:
- The false gradation in properties as we move from left to right in the periodic table is **Option 2**.
