The correct Answer is:
To solve the question regarding the atomicity and the P-P-P bond angle in white phosphorus, we can follow these steps: ### Step 1: Understand the concept of atomicity Atomicity refers to the number of atoms that constitute a molecule. In the case of white phosphorus, it is known to exist as a P4 molecule. **Hint:** Remember that atomicity is simply the count of atoms in a single molecule of a substance. ### Step 2: Identify the molecular formula of white phosphorus White phosphorus has the molecular formula P4, which indicates that it consists of four phosphorus atoms. **Hint:** Look for the molecular formula to determine the atomicity directly. ### Step 3: Determine the atomicity of white phosphorus Since white phosphorus is represented by the formula P4, its atomicity is 4. **Hint:** The atomicity can be found by counting the number of atoms in the molecular formula. ### Step 4: Understand the structure of white phosphorus White phosphorus has a tetrahedral structure where the phosphorus atoms are arranged in a three-dimensional shape. **Hint:** Visualizing the arrangement of atoms can help in understanding the molecular geometry. ### Step 5: Identify the bond angle in white phosphorus In the tetrahedral structure of white phosphorus, the bond angle between the phosphorus atoms (P-P-P) is 60 degrees. **Hint:** The bond angle can be determined by analyzing the geometry of the molecule. ### Final Answer - The atomicity of white phosphorus is **4**. - The P-P-P bond angle in white phosphorus is **60 degrees**.
