B. 1
C. 3
D. 4

Answer

To determine the number of oxygen atoms present around nitrogen in \( N_2O_5 \), we can follow these steps:

### Step 1: Understand the Molecular Formula
The molecular formula \( N_2O_5 \) indicates that there are 2 nitrogen (N) atoms and 5 oxygen (O) atoms in the compound.

**Hint:** Start by identifying the number of each type of atom in the molecular formula.

### Step 2: Draw the Lewis Structure
To visualize the arrangement of atoms, we can draw the Lewis structure of \( N_2O_5 \). In this structure:
- Each nitrogen atom is bonded to oxygen atoms.
- There are two nitrogen atoms and five oxygen atoms.

**Hint:** Remember that nitrogen typically forms three bonds and can have lone pairs, while oxygen typically forms two bonds and can also have lone pairs.

### Step 3: Analyze the Bonding
In the Lewis structure:
- One oxygen atom is in the center, bonded to both nitrogen atoms.
- Each nitrogen atom is double bonded to one oxygen atom and single bonded to another oxygen atom.

**Hint:** Look for how many oxygen atoms are directly bonded to each nitrogen atom.

### Step 4: Count the Oxygen Atoms Around Each Nitrogen
From the structure:
- Each nitrogen atom is bonded to three oxygen atoms: one double bond and two single bonds.

**Hint:** Make sure to consider both the double and single bonds when counting the number of oxygen atoms around each nitrogen.

### Step 5: Conclusion
Thus, the number of oxygen atoms present around each nitrogen atom in \( N_2O_5 \) is 3.

**Final Answer:** The number of oxygen atoms present around nitrogen in \( N_2O_5 \) is 3.
