`F_2` absorbs ........ portion of light and appear yellow and `I_2` absorbs .......... portion of light and appears violet 

Options

A. Red and Green
B. Violet and Yellow
C. Blue and Orange
D. Green and Red

Answer

To solve the question regarding the light absorption of fluorine (F₂) and iodine (I₂), we need to understand the concept of complementary colors in light absorption.

### Step-by-Step Solution:

1. **Understanding Color Absorption**:
- When a substance absorbs a certain color of light, it appears in the complementary color. For instance, if a substance absorbs blue light, it will appear red, and if it absorbs yellow light, it will appear violet.

2. **Analyzing Fluorine (F₂)**:
- The question states that fluorine (F₂) appears yellow. To determine which portion of light it absorbs, we need to identify the complementary color of yellow.
- The complementary color of yellow is violet. Therefore, fluorine absorbs violet light.

3. **Analyzing Iodine (I₂)**:
- The question also states that iodine (I₂) appears violet. To find out which portion of light it absorbs, we look for the complementary color of violet.
- The complementary color of violet is yellow. Hence, iodine absorbs yellow light.

4. **Final Answer**:
- Fluorine (F₂) absorbs violet light and appears yellow.
- Iodine (I₂) absorbs yellow light and appears violet.
- Therefore, the correct answer is: Fluorine absorbs **violet** portion of light and appears **yellow**, while iodine absorbs **yellow** portion of light and appears **violet**.

### Summary:
- Fluorine (F₂) absorbs **violet** light and appears **yellow**.
- Iodine (I₂) absorbs **yellow** light and appears **violet**.
